Kristy is in her final year of computer science at the University of Waterloo (UW). Since her enrollment, she has interned for Paypal, Cognite AS, Peggy, Cockroach Labs and Google — all as a software engineer. When she graduates, she plans to work as an engineering manager. At the moment, Kristy is a technical project lead for UW Blueprint initiative, which focuses on accessible technology and promoting public and social welfare. The initiative partners with non-profit organizations to provide websites, mobile applications and analysis tools for free. Under UW Blueprint, Kristy leads a project that builds web applications to help Planet Read coordinate volunteers to translate and review children’s stories. “Currently how they process their translations is through email and Word documents, so we’re building a platform to hopefully change that,” she says. “It’s kind of like my brainchild for the last few months and we will be deploying in [January].” Kristy’s journey to UW’s computer science program was possible through a handful of positive reinforcements. Growing up in Guelph, ON. alongside her older sister to Chinese immigrant parents, Kristy fostered a keen interest in computer science through video games and mathematics. From catching Pokemons to rummaging through online indie games, Kristy began to see the correlation of mathematics in them. “I always liked tinkering with things…it seemed like computer science was a natural concept to try out,” she says. Although in high school, Kristy did not find the computer science courses to be challenging enough, she admits having an excellent teacher was a game-changer. She is also proud that she was part of a tight-knit comradery of the few female students looking to venture into computer science careers. “It gave me a lot of inspiration to try it out myself, and I really don’t know where I’d be if they were not there,” the 22-year-old says. “I think that it was really huge for me.” Then there were hackathons. “Hackathons really connected me with the community I wanted to be a part of, I met a lot of students from Waterloo while I was in high school in the hackathon community.” she says. For Kristy, hackathons were a way for her to connect with people who wanted to build and create. What attracted her to hackathons weren’t the elaborate and complex projects, but the simple ones that embodied the spirit of learning and having fun. Throughout high school, hackathons became Kristy’s staple extracurricular, but for her it was more than just an after-school activity. In 2016, she would become the founder of SpartaHacks, introducing Guelph to the first high school hackathon, organized alongside her friends from September to December. This was Kristy’s first time organizing and finding major success. “I really wanted to give back to a community that gave me so much.” Kristy says. “My school, on a smaller level, didn’t have much of a computer science environment or community, I felt really passionate about bringing it to my school and convincing my friends to enjoy these things.” As Kristy found herself studying at UW, her passion for hackathons continued. Soon, Kristy will be working with Hack the North as a logistics organizer and backend engineer. “I wanted to find people I could relate to more, I think it’s important to be able to have people in your life who can support you in the way that you need to be supported,” she says. “It’s hard.” Kristy does not shy away from talking about identity politics in the computer science industry, including her time at UW. As a queer woman of colour, finding a space in the industry isn’t as easy as it seems. In her experience, having mentors who either are allies or individuals from your community is a way to feel connected to a stereotypically heteronormative space. “It was huge for me that I had mentors in high school, who were women in computer science.” “It’s great to have a diverse network, and be friends with people from all walks of life, regardless of the background you come from.” Kristy spoke of the hope she feels in the growth of inclusion in the industry. “I think the onus is on everyone to make the space more welcoming and inclusive,” she says. When looking at Ontario, Kristy stated that there needs to be more change in regards to learning in programming, as computer science isn’t offered in every school, public or private. This would mean providing more resources, funding programming camps and implementing programming courses in schools that are subsidized. “If you grew up in rural Ontario, where there might not even be upper calculus classes, then it’s going to be hard to get a hold of programming classes,” she says. “Having the resources and the opportunities to go to programming camp, or go to hackathons, can be really influential with that.” With the ever-growing environment of STEM careers, Kristy believes there are many ways for students and people interested in computer science to increase their skills. For Kristy, co-op programs changed her life for the better, giving her a chance to explore different paths. Kristy spent time in California and Norway where she worked remotely for international companies during the pandemic. Through these experiences, her love for startups and entrepreneurship grew. “You receive valuable hands-on experiences on building software and websites from scratch,” she says. The desire and focus to build and create is what Kristy believes is the most important factor in figuring out what a student or someone just entering the STEM industry needs. She also emphasizes the need for expanding people’s creativity, and not just sticking to one type of building. “Take time to take care of yourself, do some art, some construction, woodwork, things like that,” she says. “Those are all important in keeping the spirit of building things alive, and to keep the spirit healthy.” There’s more interesting interviews like this at Thinking Cap!

. Because one of the most common use cases of the new databases is storing data that is generated by high-throughput sources, it is important that the store engine is able to handle write-intensive workloads, all while offering acceptable read performance. RocksDB implements what is known in the database literature as a aka LSM tree. Technical design log-structured merge tree A Brief History of Distributed Databases The era of Web 2.0 brought with it a renewed interest in database design. While traditional RDBMS databases served well the data storage and data processing needs of the enterprise world from their commercial inception in the late 1970s until the dotcom era, the large amounts of data processed by the new applications—and the speed at which this data needs to be processed—required a new approach. For a great overview on the need for these new database designs, I highly recommend watching that database guru Michael Stonebraker delivered for Stanford’s Computer Systems Colloquium. this presentation The new databases that have emerged during this time have adopted names such as NoSQL and NewSQL, emphasizing that good old SQL databases fell short when it came to meeting the new demands. Despite their different design choices for particular protocols, these databases have adopted, for the most part, a shared-nothing, distributed computing architecture. While the processing power of every computing system is ultimately limited by physical constraints and, in cases such as distributed databases where parallel executions are involved, by the implications of , most of these systems offer the theoretical possibility of unlimited horizontal capacity scaling for both compute and storage. Amdahl's law Each node represents a unit of compute and storage that can be added to the system as needed. However, as Cockroach Labs CEO and co-founder Spencer Kimball explains in the case of CockroachDB, designing one of these new databases from scratch is a herculean task that requires highly knowledgeable and skillful engineers working in coordination and making very carefully thought decisions. here For databases such as CockroachDB, having a reliable, high-performance way to store and retrieve data from stable storage is essential. Designing a library that provides fast stable storage leveraging either filesystem or raw devices is a very difficult problem because of the elevated number of edge cases that are required to get right. Providing Fast Storage with RocksDB is a library that solves the problem of abstracting access to local stable storage. It allows software engineers to focus their energies on the design and implementation of other areas of their systems with the peace of mind of relying on RocksDB for access to stable storage, knowing that it currently runs some of the most demanding database workloads anywhere on the planet at and other equally challenging . RocksDB Facebook environments The advantages of RocksDB over other store engines are: . Because one of the most common use cases of the new databases is storing data that is generated by high-throughput sources, it is important that the store engine is able to handle write-intensive workloads, all while offering acceptable read performance. RocksDB implements what is known in the database literature as a aka LSM tree. Technical design log-structured merge tree Going into the details of LSM trees, and RocksDB’s implementation of the same, is out of the scope of this blog, but suffice it to say that it’s an indexing structure optimized to handle high-volume—sequential or random—write workloads. This is accomplished by treating every write as an append operation. A mechanism, that goes by the name of runs—transparently for the developer—in the background, removing data that is no longer relevant such as deleted keys or older versions of valid keys. compaction Source: http://www.benstopford.com/2015/02/14/log-structured-merge-trees/ Through the clever use of , RocksDB also offers great read performance making RocksDB the ideal candidate on which to base distributed databases. bloom filters The other popular choice to base storage engines on is b-trees. InnoDB, MySQL’s default storage engine, is an example of a store engine implementing a b-tree derivative, in particular, what is known as a b+tree. . The choice of a given technical design for performance reasons needs to be backed with empirical verification of the choice. During his time at Facebook, in the context of the project, a fork of MySQL that replaces InnoDB with RocksDB as MySQL’s storage engine, Mark Callaghan performed extensive and rigorous performance measurements to compare MySQL performance on InnoDB vs on RocksDB. Details can be found . Performance MyRocks here Not surprisingly, RocksDB regularly comes out as vastly superior in write-intensive benchmarks. Interestingly, while InnoDB was also regularly better than RocksDB in read-intensive benchmarks, this advantage, in relative terms, was not as big as the advantage RocksDB provides in the case of write-intensive tasks over InnoDB. Here is an example in the case of a I/O bound benchmark on : Intel NUC Source: https://smalldatum.blogspot.com/2017/11/insert-benchmark-io-bound-intel-nuc.html . RocksDb provides several tunable parameters to extract the best performance on different hardware configurations. While the technical design provides an architectural reason to favor one type of solution over another, achieving optimal performance on particular use cases usually requires the flexibility of tuning certain parameters for those use cases. Tunability RocksDB provides a long list of parameters that can be used for this purpose. Samsung’s Praveen Krishnamoorthy presented at the 2015 annual meetup an extensive on how RocksDB can be tuned to accommodate different workloads. study . In mission-critical solutions such as distributed databases, it is essential to have as much control and monitoring capabilities as possible over critical components of the system, such as the storage engine in the nodes. Manageability Facebook introduced several important to RocksDB, such as dynamic option changes and the availability of detailed statistics for all aspects of RocksDB internal operations including compaction, that are required by enterprise grade software products. improvements . The world of enterprise software, particularly when it comes to databases, is extremely risk averse. For totally understandable reasons—risk of monetary losses and reputational damage in case of data loss or data corruption—nobody wants to be a guinea pig in this space. Production references RocksDB was developed by Facebook with the original motivation of of its massive MySQL cluster hosting its user production database from InnoDB to RocksDB. The migration was completed by resulting in a 50% storage savings for Facebook. switching the storage engine 2018 Having Facebook lead the development and maintenance of RocksDB for its most critical use cases in their multibillion dollar business is a very important endorsement, particularly for developers of databases that lack Facebook’s resources to develop and maintain their own storage engines. . RocksDB offers a key-value API, available for C++, C and Java. These are the most widely used programming languages in the distributed database world. Language bindings When considering all these 6 areas holistically, RocksDB is a very appealing choice for a distributed database developer looking for a fast, production tested storage engine. Who Uses RocksDB? Over the years, the list of known uses of RocksDB has increased dramatically. Here is a non-exhaustive list of databases that embed RocksDB that underscores its suitability as a fast storage engine: Apache Cassandra CockroachDB MySQL (MyRocks) Rockset While all these database providers probably have similar reasons for picking RocksDB over other options, Instagram's replacement of Apache Cassandra’s own Java written LSM tree with RocksDB, which is now available to all other users of Apache Cassandra, is significant. Apache Cassandra is one of the most popular NoSQL databases. RocksDB has also found wide acceptance as an embedded database outside the distributed database world for equally important, mission-critical use cases: - In the Apache Kafka ecosystem, Kafka Streams is a client library that is commonly used to build applications and microservices that consume and produce messages stored in Kafka clusters. Kafka Streams supports fault-tolerant stateful applications. RocksDB is used by default to store state in such configurations. Kafka Streams - Apache Samza offers similar functionality as Kafka Streams and it also uses RocksDB to store state in fault-tolerant configurations. Apache Samza - After looking at several options, Netflix picked RocksDB to support their SSD caching needs in their global caching system, EVCache. Netflix - Cloudera Professional Services built a near-real-time transactional analytics system for Santander UK, backed by Apache Hadoop, that implements a streaming enrichment solution that stores its state on RocksDB. Santander Group is one of Spain's largest multinational banks. As of this writing, its revenues are close to 50 billion euros with assets under management approaching 1.5 trillion euros. Santander UK - Cherami is Uber’s own durable distributed messaging system equivalent to Amazon’s SQS. Cherami chose to use RocksDB as their storage engine in their storage hosts for its performance and indexing features. Uber RocksDB: Powering High-Performance Distributed Data Systems From its beginnings as a fork of LevelDB, a key-value embedded store developed by Google infrastructure experts Jeff Dean and Sanjay Ghemawat, through the efforts and hard work of the Facebook engineers that transformed it into an enterprise-class solution apt for running mission-critical workloads, RocksDB has been able to gain widespread acceptance as the storage engine of choice for engineers looking for a battle-tested embedded storage engine.

What’s shaping our technology world GitHub is not just a code hosting service with version control — it’s also an enormous developer network. The sheer size of GitHub at over 30 million accounts, more than 2 million organizations, and over 96 million repositories translates into one of the world’s most valuable development networks. How do you quantify the value of this network? And is there a way to get the top repositories? Here at U°OS, we ran the GitHub network through a simplified version¹ of and produced the top 100 most valuable repositories. our reputation algorithm The result is as fascinating as it is eclectic in the way that it does feel like a good reflection of our society’s interest in the technology and where it moves. There are the big proprietary players with open source projects — Google, Apple, Microsoft, Facebook, and even Baidu. And at the same time, there’s a Chinese anti-censorship tool. There’s Bitcoin for cryptocurrency. There’s a particle detector for CERN’s Large Hadron Collider. There are gaming projects like Space Station 13 and Cataclysm: Dark Days Ahead and a gaming engine Godot. There are education projects like freeCodeCamp, Open edX, Oppia, and Code.org. There are web and mobile app building projects like WordPress, Joomla, and Flutter to publish your content on. There are databases to store your content for the web like Ceph and CockroachDB. And there’s a search engine to navigate through the content — Elasticsearch. There are also, perhaps unsurprisingly, jailbreak projects like Cydia compatibility manager for iOS and Nintendo 3DS custom firmware. And there’s a smart home system — Home Assistant. All in all, it’s really a great outlook for the technology world: we learn, build stuff to broadcast our unique voices, we use crypto, break free from proprietary software on our hardware, and in the spare time we game in our automated homes. And the big companies open-source their projects. Before I proceed with the list, a result of running the Octoverse through the reputation algorithm also produced a value score for every individual GitHub contributor. So, if you have a GitHub account and curious, you can get your score at and convert it to a Universal Portable Reputation. https://u.community/github Top 100 projects & repositories Out of over 96

Apache Cassandra — The minimum internals you need to know

How can you tell which cloud provider is the right one for your business? And which one isn’t going to break your wallet? On the surface, AWS, Microsoft Azure, and Google Cloud are pretty similar. They all offer flexible compute, storage, and networking combined with everything engineers love about the cloud: self-service, instant provisioning, and autoscaling. But cloud providers differ in key areas that have a massive impact on your cloud bill. Most of your bill consists of d. That’s why I will focus on comparing the pricing of Instances and Virtual Machines across AWS, Azure, and Google Cloud to show you the nuanced differences between these providers. compute resources that represent even 75%-80% of a company’s cloud spen Cloud landscape overview: Top strengths of AWS, Azure, and Google Cloud Selecting one vendor over another comes down to knowing what your teams, applications, and workloads need. You need to have a full understanding of your requirements before setting out to explore the cloud landscape. Next, it’s time to examine each provider separately. The thing is, AWS, Azure, and Google Cloud come with different strengths and weaknesses. AWS is the leader for a good reason Let’s start with AWS that currently holds the largest chunk of the cloud market. Its undeniable strength is . You can choose from and pair them with a rich array of tools for databases, analytics, management, IoT, security, and enterprise applications. This list could go on almost forever. the sheer breadth and depth of its services almost 400 instance types AWS is the winner when it comes to developer functionality, thanks to the breadth of its services and ability to translate this scale into cost benefits. Still, this . One of the common pricing challenges companies face is understating AWS metrics and estimating the impact of architectural decisions on costs. complexity comes at a cost Azure is the go-to choice for enterprises. Microsoft Azure is quite a . That’s usually because they have a long-standing relationship with the provider and meeting all their enterprise computing needs in one place makes sense. popular choice with C-level executives The combination of Azure, Office 365, and Teams makes a safe option for enterprises looking to benefit from enterprise software all the way down to cloud computing resources with a single handshake. Google Cloud taps into the power of open source. All three major cloud vendors are strong in machine learning capabilities. But Google stands out among them thanks to its endless well of internal research and expertise – basically, the magic powering the search engine giant throughout the years. What makes Google different is its role in . I’m talking especially about containers and Google’s central role in building Kubernetes for orchestration and the Istio service mesh, today practically industry-standard technologies. developing various open source technologies Google’s culture of innovation lends itself really to startups and companies that prioritize these approaches and technologies. Naturally, companies often end up using different cloud providers for different parts of their operations or use cases. This lets them bring the best of all the (cloud) worlds together under one roof. multi cloud approach Billing in AWS vs. Azure vs. Google Cloud Per second billing is now something all the three cloud vendors offer. AWS introduced it in 2017 for EC2 Linux-based instances and EBS volumes at first – but today, it applies to many other services. Note that in AWS, per-second billing works with the minimum 60-second limit. Azure allows per-second charges as well, but this billing model isn’t available for all instances – mostly container-based instances. Google Cloud followed AWS in the introduction of per-second billing and now offers it for more than just instances based on Linux. In Google, this form of billing applies to all VM-based instances. Let’s take a look at the biggest cost driver: compute Compute is what makes your cloud bill so high. This isn’t to say that other services don’t contribute to it at all. Storage can get quite expensive, and moving data around might result in high egress costs. But it’s compute that comes with the biggest price tag – and greatest opportunity for cost optimization. Here’s a case study that shows the . incredible impact optimizing compute costs can have on a company’s bottom line How Netflix slashed its cloud costs by picking different machines To deliver its video streaming services across 190 countries, uses Amazon EC2 instances and Kinesis data streams. Recently, Netflix turned to the Graviton2-based EC2 instances. Switching to these brand-new machines helped Netflix improve performance by 50% and cut costs. Netflix Before, the company used m4.16xlarge instances that cost $3.2/hour. Now, Netflix uses m6g.16xlarge that costs $2.464/hour, and m6g.xlarge, priced at only $0.0154/hour. You can only imagine the cost savings Netflix enjoyed on its cloud billing. This example clearly shows how a minor difference in instance pricing can save you thousands of dollars. Comparing cloud pricing – our example setup To understand the pricing differences better, we’re going to compare instances and VMs within one region and across the same operating system. This is our example setup: Region: US West – Los Angeles (US West in Azure, US West 2 in Google Cloud) Operating System: Linux vCPUs: 4 Types of instances/VMs we will analyze: General-purpose Compute-optimized Memory-optimized For our comparison, we chose instances with similar RAM and 4 vCPUs. The obvious exception is Google Cloud’s memory-optimized instance that starts at 40 vCPUs. Here are the instances/VMs we selected for our cloud pricing comparison: AWS vs. Azure vs. Google Cloud: Comparing On-Demand pricing Here is the hourly On-Demand pricing of each of those instance-type scenarios across AWS, Azure, and Google Cloud. Cloud pricing based on On-Demand rates Note: In the above table, red marks the highest price and green the lowest price for a given instance type. Takeaways: As you can see, AWS and Azure offer quite a similar pricing for all these three instance types. For compute-optimized instances, Google Cloud has the highest pricing due to its scalable processors and all-core performance. The cost of Google Cloud for memory-optimized instances is way higher because it doesn’t run on 4 vCPUs, but 40vCPUs.A note about chips and processors Providers roll out instances on different computers, and the chips in them have different performance characteristics. So, you might end up with an instance type that has strong performance your teams don’t actually need, and you’ll have no idea about this. Reasoning about this on your own is challenging, and the best way to see what you’re really paying for is via benchmarking. The idea here is to drop the same workload on each machine and check its performance characteristics. You might discover something interesting, just like we did: This chart shows CPU operation in AWS (t2.2xlarge with 8 virtual cores) at different times after several idle CPU periods. Would you expect such unpredictable CPU behavior within a single cloud provider? Source: CAST AI The used the same method to evaluate 54 machines across AWS, Azure, and Google Cloud. They ran over 1000 microbenchmark tests to evaluate metrics like CPU, network, storage, and TPC-C performance. 2021 Cloud Report from CockroachLabs t achieved the best single-core CPU performance and offered the greatest throughput at every level. Google’s machines with general-purpose disks achieved the highest level of raw throughput but turned out to be the least cost-efficient option. One of their overall conclusions was that Google beats AWS and Azure on performance. I AWS vs. Azure vs. Google Cloud: Comparing discounted pricing with 1-year upfront commitment All three providers offer discounts if you commit to using them for at least 1 year. The pricing model is called Reserved Instances/Savings Plans in AWS, Reserved Savings in Azure, and Commitment Price in Google Cloud. These discounts incentivize businesses to commit to a specific level of usage for a fixed period in exchange for a discounted rate on some (not all) instances and VMs. To compare the discounted pricing among AWS, Azure, and Google Cloud, we examined a one-year commitment period without upfront cost – but this time, in another region: US East – Northern Virginia. Cloud pricing with 1-year commitment Takeaways: The general-purpose instances with a 1-year commitment are almost similar in AWS and Azure. AWS wins in the compute-optimized category, even if Azure and Google apply some pretty big discounts. Azure offers the cheapest alternative among memory-optimized instances. Not sure how Reserved Instances work and whether they really translate into discounts? Read this: Do AWS Reserved Instances and Savings Plans really reduce costs? How CPU bursting can help drive your costs down AWS, Azure, and Google Cloud all offer burstable performance instances. These instances provide you a baseline level of CPU performance, with the opportunity to burst to a higher level whenever your workload requires that. Burstable performance instances are . a good pick for low-latency interactive applications, microservices, small and medium databases, or product prototypes But to make the most of them, you need to keep a close eye on the credits you collect that enable bursting. For example, if you restart a T2 instance in AWS, you’re going to lose all the credits. Restarting a T3 or T4 instance means keeping credits for another 7 days and then losing them. Our research into AWS burstable instances showed that if you load your instance for 4 hours or more per day on average, you’re actually better off with a non-burstable one. But if you run an e-commerce business that gets a large stream of visitors once in a while, it’s a good match. AWS vs. Azure vs. Google Cloud: Comparing Spot Instances/Preemptible VMs Here’s another way to reduce your cloud bill – take advantage of capacity that’s currently not being used by any businesses. Cloud providers sell this excess capacity at incredibly high discounts – while AWS Spot Instances offer up to 90% off the On-Demand rates, Preemptible VMs in Google can be even 80% cheaper than regular VMs. Here’s a quick overview of the potential savings you can get for these instances in the US East – Northern Virginia region: Cloud pricing with Spot Instances/Preemptible VMs As you can see, all providers offer substantial discounts on these instances. But to take advantage of these savings, . How? Here’s a step by step guide: you need to make sure that your applications can handle interruptions Spot Instances: How to reduce AWS, Azure, and GCP costs by 90% Optimizing cloud costs is a point in time exercise By now, you’ve learned the basics of calculating compute charges. But Spot instance prices don’t always stay the same. In fact, they might change from one second to the next. Take a look at this example: At CAST AI, we were running an application on a mix of AWS On-Demand instances and Spot Instances. Then we used our own platform to analyze our setup. The platform looked for the most cost-effective Spot Instance alternatives for a machine with 8 CPUs and 16 GB. CAST AI suggested that we run our workload on an instance called INF1. But wait, It’s a supercomputer that usually costs a lot of money. why would we need a powerful GPU instance meant for machine learning applications? So, why did CAST AI pick it? We checked the pricing. As it turns out, at that time, INF1 just happened to be cheaper than the usual general purpose instances we used. We would have never guessed to look for Spot Instances in this category. As a result, we’d miss out on this incredible gem. That’s exactly the reason why you need automation to optimize cloud costs Even if you have DevOps or FinOps specialists managing your cloud expenses, .
