Every entrepreneur dreams about creating a perfect product. This superior product has fully automated delivery pipelines and robust hardware/software, running like clockwork and never failing. And to make a dream come true, businesses seek DevOps professionals. But is this story about DevOps? Indeed, practices answer what to do, why, and what tech stack to use. The thing is, DevOps gives you recommendations, and their implementation falls under the SRE responsibility. DevOps The Three Letters The term comes from Google and stands for site reliability engineering. The of the concept is encrypted in its title – making things work reliably. principal value SRE is a priceless practice for . It’s about managing massive infrastructure through code (which is more sustainable for system admins who deal with hundreds of machines). creating scalable and highly reliable software systems The concept uses to ensure excellent system management, fast problem solving, and operational efficiency. DevOps-related tools and practices Embracing (SLAs), SRE defines the required reliability of the system through (SLIs) and (SLOs). service-level agreements service-level indicators service-level objectives The SLO is based on the SLI – organizations set SLOs to the point where unreliability causes customer pain. The SLO should be monitorable to give maximum efficiency. The SRE concept likewise refers to and reflects its inner side: engineers work with indirect business needs to deliver outstanding client experience. Involving SRE teams in traditional IT support allows companies to run it in a DevOps way – this describes the idea in detail. tech support article Let’s get back to site reliability engineering. The purpose is clear – but who is responsible for realization? Site Reliability Engineers in organizations are often called Deployment Engineers. They are the ones to cover reliability, being responsible for pre-release audits and release schedules. Moreover, an SRE department is in charge of code deployment, configuration, monitoring, availability, emergency response, and capacity management. DevOps practices answer what to do and why, while SRE executes these suggestions using a proper tech stack. How about focusing on the ways of implementation further on? Let’s sum up a bit: Best Practices Since some SRE principles overlap with the DevOps mindset, don’t be surprised when facing automation or monitoring. The following five concepts will help you improve digital operations in multiple areas, be it manufacturing or hospitality. Automate Our team emphasizes that automation is the king among DevOps or SRE practices – organizations use it to free up resources for other business needs. In contrast, teams aim at easing processes and decreasing the amount of repetitive work. Speaking of automation, it can primarily help you in Delegate server creation or switch between codebases to a machine, configure proper tooling to find bugs instead of humans and automate runbooks to respond to incidents quicker. Don’t hesitate and reduce human intervention to benefit from effectiveness and higher velocity. incident management, testing, and deployment. Simplify Leonardo da Vinci said, “Simplicity is the ultimate sophistication”, – and we can’t but refer to this idea when talking about SRE practices. , so consider creating plain environments to track and fix bugs or improve them without difficulties. SRE highlights simplicity to achieve reliability and refinement Suppose you already benefit from any system – check it for the areas of redundant complexity and optimize high toil ones. In that case, such an inspection will also help reduce the amount of repetitive work. Venture Embracing the latter allows companies to manage budgets and resources wisely. Building excellent reliability requires money, time, energy, and risk. Split improvement areas and set up a budget and a minimum acceptable reliability level for each. Сorrelate the cost of improvements and their impact on client satisfaction. The book by T.Panaggio, , claims that “the unexpected edge for entrepreneurial success starts with identifying a worthy risk and then having the courage to take it.” So act decisively but always weigh potential risks before doing anything. The Risk Advantage Release Should I point out the necessity of stable and continuous builds and deploys for successful software development? comprise configuration management, automated testing, continuous integration, monitoring, and documenting each stage – the majority of SRE practices, as you can see. Modern quality standards Teams, therefore, need to choose single release standards, build guidelines, set up a monitoring system and automate as much as possible if they want to benefit from site reliability engineering. Monitor And last but not least – notorious monitoring. Watching metrics and gathering data allows teams to and fix bugs before reaching the end-user. And the system analyses metrics to answer what’s broken and why constantly. understand the health of the systems ideal monitoring When setting up monitoring, connect alerting tools to monitoring data and scan the entire system for possibly threatful patterns. is key to an effective process establishment. Choosing proper tooling When selecting a tool, make sure it’s a qualitative one. Consider (excellent soft watches them in a context) and (any superb instrument offers this feature). spikes in metrics virtualization So, having embraced this vital SRE and DevOps practice, you’ll know whether your system is ready to handle high traffic or your website’s load time. Summary DevOps and site reliability both emphasize cross-team communication, shared responsibility, and automation – however, . these mindsets are not identical DevOps is a broader philosophy applied to multiple technologies, while SRE has a tight focus: the latter is about a unit assigned to a specific project or tech stack. The SRE monitors the metrics valuable exclusively for a given case when DevOps watches all possible parameters. Let me put it in a nutshell: And at Corewide, we are experts at both. Mixing traditional ideas with a DevOps philosophy seasoned with SRE practices boosts tech performance and establishes stable business growth. SRE is the DevOps implementation itself. Indeed, the outcome is brilliant - try it yourself.
