Though DevOps, DevSecOps and SRE, all three techniques serve the same basic role of managing the development infrastructure but their semantics are different. There are some subtle dissimilarities between all the practices that may seem insignificant but they lay the fact that all of them fulfil diverse business needs. Interpreting those different characteristics is guide to ensure that the IT team of an organization adopts the appropriate technique and operates efficiently.
What is DevOps?
DevOps is a union of development and operations. It is not only amalgamation of IT operations, individuals and technology across both departments but adopting an environment that involves automated infrastructure deployment and maintenance. DevOps additionally includes changes in cultural environment after merging the two departments.
The benefits of DevOps
Adoption of DevOps ensures faster and effective deployment of technical updates that satisfies the needs of customers as well as organization. It significantly improves the quality of service that the organization provides by maintaining the transparency of the process. It also reduces the management and production cost by bringing two different departments under a single umbrella.
What is DevSecOps?
DevSecOps is integration of security in DevOps framework. It ensures the secure workflow of DevOps by selecting the right security tools and parameters. It helps the DevOps to analyse the risk and benefits of every process before implementing it and guaranteeing security at every step.
The benefits of DevSecOps
DevSecOps allows better association and communication among teams which increases efficiency and agility. It prevents unexpected downtime and security issues that slow down operations by identifying vulnerabilities at early stage.
What is SRE?
Site reliability engineering is a software engineering methodology to manage IT operations. The SRE teams implement automatic solutions to intense issues. SRE offers scalable and sustainable approach to sysadmins to manage huge systems.
The benefits of SRE
SRE improves automation and communication between developers and sysadmins. SRE team ensures secure system health and build an on-call process. They bring up the production concerns to create an effective product roadmap. They constantly identify the areas of improvement and offer constructive solution.
Difference between DevOps and DevSecOps
DevSecOps and DevOps, both play a significant role in an environment where software upgrades are usually executed several times daily and obsolete security models can’t sustain it. Where DevOps focuses only on effective deployment of upgrades, DevSecOps address the security concerns along with deployment. DevOps is only responsible for operational tasks related to single project but DevSecOps implies that security is everyone’s responsibility.
Difference between DevOps and SRE
DevOps reduce silos whereas SRE are not concerned about the existence of silos in the company. Where DevOps embrace the unexpected failures, SREs main objective to ensure no failure happen at all. While DevOps implement technological changes effectively, SRE keeps check on failure cost as well. Automated workflow needs constant monitoring, in this process DevOps team ensures softwares are working effectively whereas SRE believes that operations is a software issue. SRE practice involve contribution from every level of organization whereas DevOps is all about development and operations only.
