Software deployment pillars the software development life cycle (SDLC). It links users and developers, making it possible to gather and use feedback fast. This feedback loop raises software's quality, usability, and scaling propensities. However, software deployment is challenging and requires careful planning and strategy. As a result, the deployment process's design has to be carefully considered. The effectiveness of the planning phase may determine whether a deployment is successful or unsuccessful. ”Your solution doesn’t work till others can use/tinker with it. Deployment enables that.” In this article, I delve into the specifics of the planning stage of software deployment and provide an accurate walkthrough of everything that must be established. Although there are many different deployment methodologies, the DevOps methodology is the focus of this article. What Is Software Deployment? Software deployment is the method by which applications, modules, updates, and fixes are distributed from developers to target environments. Pushing software into target environments entails actions that increase functionality, such as system management and operations. Deployment is the anti-penultimate stage of the SDLC. Software production is frequently confused with software deployment. Although used synonymously, they have different meanings. Software production is more comprehensive; it involves several activities, including code and build development and deployment. Software Deployment Activities Software deployment is an amalgam of numerous activities that can be summed into five major headings: Planning Deployment: Adequate planning is the primary driver of successful software deployment. This article explains that. Verifying service components Verifying target environments: Depending on your operating system and the size of your project, there are different ways to verify target environments. No matter the operating system, you must configure and create a target connection between your local machine and your target environment before deploying the software package to the target to carry out your planned functions. For instance, on Linux, you can configure and set up a target connection using a real-world NFS target networking environment, an emulated target environment, or a flash development environment. To ensure that the software functions correctly in the target environment, dependencies are also installed during this phase. Executing deployment: For DevOps, this is the phase of implementation of DevOps’ principles like all-around automation, CI/CD, etc. Confirming deployment: More than deployment is required. Confirmation is essential to ensure that the software package has been successfully deployed. Planning for Software Deployment Adequate planning facilitates the convergence of all parties involved in the software deployment process into a single source of truth and improves communication. Good planning has implementation-based advantages as well as corporate or organizational advantages. In this article, I divided the planning process into two main functions: managerial and engineering activities. Engineering Activities The engineering team generated the code, versioned it in the most practical format, and prepared the package for distribution because they are the software's backbone. The technical department must cater to six components: frontend, backend, monitoring, CI/CD, data storage, and security. Prepare your software package for deployment by doing the following: Frontend Minify CSS and JavaScript files, and compress images to reduce the number and size of files your software has to load when deployed. Configure a content delivery network (CDN) to reduce network latency. When a user initially requests access to your software, a CDN server guarantees that the files are transferred from the origin server, a copy of the assets is cached on the edge server, and the data is reused for subsequent requests. Users may get your application more quickly in this fashion, and your deployment host won't become overloaded with requests. of websites use . 79.9% Cloudflare Configure cache busting by versioning your files when they’re updated. Cache busting guarantees that the most recent updates to your software are generated and immediately made publicly available. Three techniques exist for performing cache busting: File name versioning (e.g., style.v2.css) File path versioning (e.g., /v2/style.css) Query strings (e.g., style.css?ver=2) While the first two techniques are hitch-free, cache busting using a query string may present a number of issues, especially when used with a CDN. Backend On the backend, ensure the following: To ensure that your software has sufficient resources, configure your virtual machines, HDD, CPU, and RAM. If your software is running on EC2, ensure to build an Amazon machine image (AMI). An AMI enables you to create virtual servers — e.g., EC2 instances — inside the AWS infra. You can easily create an AMI from an EC2 instance, register the machine image, and search for it when you need to launch new instances. If containerization is employed, prepare and push your images to the container registry. You can simply do this using the `$ docker push` command. The docker documentation portal contains comprehensive details on how to push a new docker image to a docker registry. If your software is packaged as microservices, configure a container orchestrator. is one of the best known, with comprehensive community support. Kubernetes Data Storage Set up relational databases. has of the relative market share in database management tools, and you can learn how to set up a MySQL database schema . MySQL 44.04% here Set up queue systems to reduce the server and data volume. Run schema migration. Schema migration auto-updates your database scheme per every change in your codebase. Set up file storage: Where will files generated during app usage be stored? Configure tools, like , and , to store these files. Amazon S3 Cloudinary Security For the security of your software, To encrypt your server connection, obtain and configure SSL certificates. Configure static code analyzers to uncover security risks in your codebase or dependencies. CI/CD CI/CD is the cornerstone of the DevOps methodology. Ensure the following: Create a deployment pipeline using a version control system (VCS) like on your remote system. Git Write test scripts and run automated tests. The cornerstone of DevOps is automated testing, and technologies like Lambdatest, TestSigma, and others that are available right out of the box let you execute automated tests in parallel across several environments. There are three ways to construct a test script: using data scripting, using a programming language, or using the record/playback approach. Scripts often include a set of instructions that detail the software functionalities that must be tested as well as the direction in which you want the automated testing to go. Set up static code analyzers. Based on pre-established principles, static code analysis tools analyze your code, format, and lint. This makes it possible to guarantee that the code adheres to current standards. Set up deployment environments. Depending on the purpose of your deployment, you could either set up an ephemeral or permanent environment. Aptible’s hosting platform automates the work of provisioning, managing, and scaling infrastructure, so I recommend Aptible here. Use a load balancer to create a zero-downtime deployment strategy. A load balancer serves as the "traffic cop" in front of your servers, distributing client requests across all servers equipped to handle them in a way that maximizes speed and capacity utilization. The load balancer routes traffic to the active servers in case one server goes offline. The load balancer initiates requests to a new server when it is added to the server group. By distributing requests only to servers that are active, a load balancer assures high availability and dependability and offers the flexibility to add or remove servers as needed. Your future scaling problems are made easier by this. Monitoring Set up log management systems to gain first-hand access to information useful in improving the deployment process. Gathering and utilizing the reports generated by the log management systems is a core component of observability, which makes your pipeline more intelligent and fool-proof. Using tools like or InfluxDB, you can monitor your processes and get error reports in real-time. The P portal has robust information on how to set up its alert management and log monitoring solutions. Prometheus rometheus documentation Managerial Functions Along with the engineering operations, a number of other essential activities include: : Team members should be familiar with both successful and unsuccessful deployment processes before deployment. The modern implementation of the DevOps deployment methodology requires that team members track the performance of the deployed software using different KPIs. Setting key performance indicators (KPIs) These KPIs enable the team to assess the progress or failure of the deployment. However, despite their importance, only a few teams monitor their deployment through KPIs. These KPIs include deployment frequency, failed deployment rate, change volume, memory use, CPU utilization, downtime during deployment, page load time, mean time to recovery (MTTR), error frequency, and many others. : Release notes serve as documentation for prospective future use and deployment explanations. Isolating unexpected problems helps to better identify them. Each deployment should be versioned to keep errors transparent and manageable. Preparing a release versioning and release notes process : Even with meticulous planning and precise automation, unforeseen events might still cripple the deployment operation. If there is a problem with the deployment process, the rollback system enables retrieval of an earlier version. Imagine it as an airbag; the ability to revert to a previous release will be crucial if the current deployment fails. Preparing a rollback system : The deployment must be carried out step-by-step and under control, allowing you to decide whether to move forward at each checkpoint. Therefore, activities set to our current checkpoint can be worked on using resources, but tasks that come after the checkpoint cannot. Hence, the next set of functions is released when the checkpoint has been passed OK. Below is an example of a task list: Preparing a task list Conclusion The success of software deployment depends on how well the planning stage, which comes before actual deployment, is executed. Planning, therefore, requires a lot of thought and attention to detail. The intricate details of the software deployment planning phase have been covered in full in this article. You are prepared to deploy if you have it in your arsenal!

53 Stories To Learn About Gitlab

Note: This article was included in the by LambdaTest and also in of Software Testing Notes. 136th Coding Jag Issue #82 Greetings to all Cypress enthusiasts! A couple of days ago, I was approached by a member of our on Discord with a question about how to validate data from an file using Cypress. This prompted me to write this article. Cypress community Excel Looking ahead, I’ll just note that this is a rather simple matter, and is mainly based on setting up the corresponding event inside the Cypress configuration file to convert the original file to format and further work with the resulting file. But first things first. Node Excel JSON If you are not yet familiar with : Cypress Cypress is an open-source JavaScript-based testing tool designed for modern web test automation. Cypress has emerged as a popular end-to-end testing tool for web applications due to a bunch of its powerful features, user-friendly interface, fast test execution time, easy installation and debugging, etc. Cypress is a real game changer in e2e and component testing, and it grows at a rapid pace. And as you may have noted from my previous articles, I’m a big fan of that wonderful tool! However, it is obvious that Cypress is not intended for testing data, which in some test scenarios, can create some inconvenience if you need to validate data in files. Excel Excel Despite this, Cypress provides a way to do this, as I noted earlier, by converting the file to Cypress-compatible format. Excel JSON This allows you to test your source data using the same test suite that you use to test your web applications. Well, let’s imagine that in the course of executing some test scenario, we get a certain file in the directory of our project. In essence, the scenario can be anything, as well as the initial location of the initial file. And now, we need to test the data in this file. Excel cypress/downloads For example, I have a file in the directory companies.xlsx downloads with the data of some 10 non-existing companies: First, let’s convert the original file to format. Actually, there are several suitable for this, the most popular of which today (judging by the number of weekly downloads) is . companies.xlsx JSON npm packages SheetJS Let’s install it into the project by typing the following command in the terminal: > npm i xlsx Next, using the syntax of this package, let’s add a event to the function in the file. This will allow us to move from the browser environment to the environment and execute some functions in this environment. task setupNodeEvents cypress.config.ts Node JavaScript For example, let’s call our function , and with its help, we will convert the original file into format: convertXlsxToJson Excel JSON So, our function takes as an argument the to the original file — and uses method to read the file, as a result of which we get a certain object with a rather complex structure containing the data of the original workbook. Let’s analyze it in more detail. convertXlsxToJson path Excel filePath XLSX.readFile() workbook Excel The main element of object is object, whose properties are also objects containing the individual worksheets in the original workbook, where the are the names of the worksheets and the are the objects that represent each worksheet. workbook Sheets Excel keys values In turn, each worksheet object has its own set of properties, whose are references to cells in the worksheet (for example, , etc.), and the are objects containing information about the type of data in a particular cell, and also the value of the cell itself. keys A1, B2 values Also, object contains array with the of the worksheets of the initial book, while the order of the names in the array corresponds to the order of the worksheets in the workbook. workbook SheetNames names Excel In addition, object also includes a bunch of other properties that contain data about the original workbook. workbook Excel To retrieve the of the worksheet that includes the companies data table (obviously, it could have been any other worksheet), we access the value of the element of array. name first null SheetNames Next, using the obtained sheet name as the of the corresponding property on object, we get the worksheet object as the value of this property and put it in variable. key Sheets worksheet On the specified variable, we apply method to convert the worksheet data to format. As a result, we have an array of objects , in which each object corresponds to a specific row of the initial table. XLSX.utils.sheet_to_json() JSON jsonData Excel The properties in each object include the column headings and the corresponding data in the cells . Ultimately, our function returns array as the result of the event. (keys) (values) convertXlsxToJson jsonData task In general, at this stage, the task can be considered complete, since the variable contains data in format suitable for use in tests. However, let’s imagine that we want to write the received data as a file and place it, for example, in the directory. jsonData JSON companies.json cypress/fixtures To do this, we supplement our function with the following lines of code: convertXlsxToJson Firstly, we define variable, in which we place the name of the original file (without extension), obtained based on the value of variable using method. fileName Excel filePath path.basename() Using the specified file name, we set variable to the path to the resulting file in the directory. jsonFilePath JSON fixtures Finally, we use method from Node.js built-in module, which synchronously writes data to the resulting file as a -formatted string with 2 spaces for each indentation level using method. writeFileSync() fs JSON JSON.stringify() Thus, we set up our event in such a way that it accepts any file located at the specified , reads it and converts it to format, and also writes the resulting file to directory. task convertXlsxToJson Excel path JSON JSON fixtures Now, to test the original data of ten companies, let’s create a file in the directory. First, let’s add hook to our test suite, in which we will call our event, passing it the to the initial file as an argument: spec testExcel.cy.ts e2e before task path Excel After calling our event, the resulting file will be written in the directory: task companies.json fixtures with the following structure: After adding the tests, finally, our file will have the following content: spec So first, we define two variables: — the path to the original file and — the name of the final file, obtained based on the value of the variable using the and methods. xlsxPath Excel jsonName JSON xlsxPath path.basename() replace() Next, inside the hook, we use the command to load the contents of the resulting file as a , which we to access the specified content in each test. beforeEach cy.fixture() JSON fixture alias companiesData As possible examples of tests, I have given rather primitive demo tests. So, the one checks if our test file contains data for companies. The verifies that each company’s data contains values ​​for the four keys — “Company Name”, “Product”, “City”, and “Email”. three first 10 second non-empty And the test checks if each company’s data contains a email address. last unique Let’s run our tests in the Cypress test runner with the standard command: > npx cypress open We click on the name of the file in the test runner window and voila — our tests were completed successfully in less than seconds: spec 0.1 Final Thoughts Although Cypress can be used to validate data, this is obviously not the case for its core functionality. Cypress does not test files “under the hood”. Excel Excel Therefore, you should be aware of possible errors that may occur at the stage of converting an file to format, such as formatting errors, data loss, etc., which can subsequently lead to undesirable results. Excel JSON Despite the relative rarity of the described case and the comparative simplicity of the approach to solving it, I really hope that this article will be useful for improving your testing skills with Cypress. That’s about it. If you found this useful, share it with a friend or community. Maybe there’s someone who will benefit from it as well.

Releases: The Last Frontier of Standardization As software engineers, we strive to better our craft and leave a lasting mark on the organizations we work for. Throughout our careers, we balance two types of knowledge: the combination of business domain and technical stack is our bread and butter. Sometimes we might value the business domain over the technical stack and vice versa as we expand our toolkit. For example, we might work at a financial institution (let’s call it Acme Investment Bank) for a broad domain, but where the tech stack is not bleeding edge. On the other hand, we might roll the dice and work for a firm that has a bleeding-edge tech stack but where the domain is very specific, like a company that sells wine to your pets. 3. Delays in app delivery to Kubernetes Enterprises around the world are waking up to the containers and Kubernetes trend. There are numerous benefits of delivering an application as container packages to Kubernetes but at the same time, the process of app containerization and the subsequent app deployment to Kubernetes can hit many roadblocks. Since the idea of using Kubernetes and containers for app delivery is fairly recent, the transition from traditional delivery systems to these modern delivery systems is a bumpy ride. 4.
