Over the years, organizations that find it difficult to scale their technology processes and operations have come to rely upon techniques including DevSecOps, DevOps, and SRE across multiple sites. Nevertheless, the task of managing development-related infrastructure and infrastructure upgrades is often very challenging. It requires the use of infrastructure-as-code, or API management for easy installation, scaling, and configuration changes.
But what is the difference between DevOps, DevSecOps, and SRE? One could argue that’s essentially a matter of semantics. Understanding the distinctions is crucial to ensuring that your IT teams operate as efficiently as possible.
So, What is DevOps?
Just as the term implies, DevOps is all about bridging the chasm between development and IT operations. It is a powerful blend of development, quality assurance, operations, and related practices and methods. The method, when properly deployed, can help everyone make the software code more “dependable”. It can also allow the code and delivery process to be more stable and less prone to system failures and cyber-threats. The primary goals of DevOps are to curtail the Software Development Life Cycle (SDLC), fast-track the delivery of the product to market, and enhance responsiveness to market needs. DevOps implies a continuous communication cycle that calls for the building, testing and installing releases to automate to a certain extent. The main objectives of automation are to cut down the market delivery of the product, shorten the time between the releases, decrease the Mean time to Repair (MTTR), and boost the quality of the release.And, What is DevSecOps?
A relatively new term in the application security space, DevSecOps, is short for development, security, and operations. It is the philosophy of integrating security practices within the DevOps process. DevSecOps requires a change in culture, process, and tools across the core functional teams, including development, security, testing, and operations. Any increase in speed and frequency of releases often leads to traditional application security systems finding themselves in a rut. It is hard for them to keep up with the pace and ensure that the release is secure. To address this situation, organizations need to build security across SDLC so that the DevOps teams can deliver secure applications with quality and speed. With the help of DevSecOps, organizations can seamlessly integrate security into their existing Continuous Integration and Continuous Delivery (CI/CD) practice. DevSecOps encompasses the entire software development life cycle (SDLC), from planning and design to coding, constructing, testing, and release, with real-time continuous feedback loops and insights.Then, What is SRE?
SRE (Site Reliability Engineer) has everything to do with creating a bridge between development and operations. SRE’s unique approach to this is to implement a software engineering mindset to system administration topics. Originated at Google, the Site Reliability Engineer term takes the de facto role of quality assurance on a DevOps team and aligns it directly with testing. For this reason, one will often see SREs utilizing Google-specific tools like Google Test suite. Site reliability engineers perform SRE, also called service reliability engineers. These professionals are usually software developers with operations experience up their sleeves. They can also be IT professionals armed with development skills. These site reliability engineers join forces with other engineers, customers, and product owners to yield targets and measures. Such a process helps in ensuring system availability. You, as a manager, quickly gets to know when to act once you’ve agreed upon a system’s uptime and availability. This whole process executes through Service-Level Indicators (SLIs) and Service-Level Objectives (SLOs). SRE’s main objective is to solve problems between teams, and the expectation is, both the SRE teams and the development teams get a complete view of libraries, front end, back end, storage, and all the other components.The Real Distinction Between These Three
The foundation for DevOps, DevSecOps, and SRE has the same roots, which is to allow successful Continuous Integration and Continuous Delivery. With companies worldwide steadily moving towards cloud and virtualization, it is becoming difficult to run many environments. Such a difficulty leads to latency, concerns, and potential slowdowns. On the outside, installing an application and then running it may look like it is absolutely the same as using it and rerunning it. In reality, though, it is very different. DevOps prioritizes delivery speed, and DevSecOps changes security to the left; SRE’s prime focus is to automate most completely, if not all, of the tasks to ensure reliability in the systems. While DevOps and DevSecOps are all about the “What” needs to be done, SRE answers “How” you can do it. It’s all about expanding the theoretical part to an efficient workflow with the right work tools and methods. It’s also about sharing the responsibility between everyone and aligning everyone with the same goal and vision. DevOps focuses on creation and testing, which includes moving the code through the pipeline effectively and efficiently. And DevSecOps is about not only making software easily deployable but making the process of installing it more secure and usable. On the other hand, SRE focuses on forming a balance between site reliability and the need for new features.But Which One is Better: DevOps, DevSecOps, or SRE?
The ability to develop and deploy a new product or re-create an existing effect within hours of starting a project is one of the significant advantages of leveraging DevOps, DevSecOps, or SRE for delivering software. It enables a developer to focus on building and developing the product, using a new team to make it production-ready, and launching the new product to end-users relatively quickly. Despite the differences between DevOps, DevSecOps, and SRE, all three help combine developer and operation teams while sharing similar responsibilities and focusing on enabling automation and reliability. In the end, it’s all about the data. All you need is information to understand how to measure success and failure and gain continuous reliability across the application.
