Embrace valuable operational benefits by adopting SRE (Site Reliability Engineering)
Enterprises are choosing Cloud adoption services as it has become a strategic priority for enterprises due to the flexibility it offers for infrastructure and IT operations management as compared to on-premise infrastructure management. Difficulty in managing legacy systems and working with decades old technologies have proven expensive and of low business value while also being unreliable at crucial times.
As cloud covers almost all the pitfalls of legacy IT systems, enterprises have been able to reach the market faster due to the resiliency and scalability it offers. But these benefits do come with complex management issues when an enterprise starts growing and adds more IT systems in their IT landscape.
Advantageously, there are modern approaches when it comes to managing IT operations on cloud because the underlying IT infrastructure is the foundation of a cloud platform that needs to be always stable. And so, to ensure all the services on cloud are always stable and reliable, organizations are taking a holistic transformational approach by adopting SRE (Site Reliability Engineering).
What is Site Reliability Engineering (SRE)?
It’s a modern software engineering approach taken by software developers and implemented on IT operations. Focus is to automate any manual tasks such as servicing applications or keeping a production environment stable through software engineering. Previously, such tasks were undertaken by an operations team but since the rise of newer software development practices, certified SRE engineers are responsible for operations automation.
In general, site reliability engineering services looks to bridge the gap between business, development, and operations teams to ensure the reliability of the systems and are responsible for availability, latency, performance, efficiency, change management, and monitoring. Reliability engineers have strong development skills and practice software development by writing a well-written software scripts compared to traditional clumsy shell scripts. Their combined expertise in infrastructure and software development is what makes them all-rounder in monitoring on-going services and addressing issues which may arise.
Site Reliability Engineering focuses on:
✓ Skills that are geared towards automation, deployment, configuration management, monitoring, as well as analytics and metrics
✓ SREs teams look to partner with engineering stakeholders to design and deliver a reliable, scalable, secure, and performant platform
✓ Reliability engineers and SRE teams look for ways to improve the customer experience and stay on top of technical trends to find innovative tools and approaches to solving problems.
It is important for organizations to first identify why they should embark on the SRE journey and expect a shift in mindset throughout the organization. By clearly defining the end goals, an organization should involve the relevant decision makers and then try to fill the gaps through SRE services.
When an organization is convinced about implementing SRE reliability engineering, they need to know what to operationalize and how to measure the goals for creating reliable systems. By using metrics such as Service Level Objectives (SLOs), Service Level Indicators (SLIs), and Service Level Agreement (SLAs), Site Reliability Engineers ensure that their systems are reliable enough to deliver high performance of the end user as agreed. Depending on what an organization is trying to achieve through SRE, these metrics can be applied to the existing issues to understand how exactly SRE can solve it and what business value does it offer.
Below listed are some of the points which act as ‘Triggers’ for organizations to choose SRE:
✓ Enhance operations – Major goal for IT heads is to improve IT operations for maximizing revenue and service availability through Site Reliability Engineers who develop software codes for smooth operations
✓ Automation – IT heads wish to automate repetitive tasks, testing, continuous integration, operational challenges, etc. to reduce the overall costs and optimize resources for better roles
✓ Cultural change – Leadership team wants to bridge the gap between IT operations and development teams by implementing SRE with DevOps site reliability engineer
✓ Reliability – Need to drastically decrease the downtime of systems and failure rates by improving system availability through SRE
✓ Lack of monitoring – Maintaining service availability and identifying performance issues is a priority for IT heads as they wish to measure uptime and health of their systems
Building SRE teams whose primary focus will be on solving the above issues can strengthen an organization’s IT operations functions by following an engineering mindset. With a deeper focus on developing scalable and reliable services, SRE teams offer various benefits to an organization looking to use software engineering to solve operations and IT issues.
Benefits of using Site Reliability Engineering:
Bridging the gap between developers and operations
Site Reliability Engineering resolves the collaboration issues between development and operations teams by bringing their focus together on software development. When SRE teams work on stability of systems and developing reliable softwares, they eliminate the need to have 2 separate development and operations teams.
SRE aims at developing solutions that continuously optimizes the reliability of products and services. Reliability engineers keep on improving this process which drives greater efficiency and stability across multiple teams, processes, and services. SRE teams also put emphasis on future requirements by developing software through enhanced best practices.
Automation, wherever possible
Administrating systems is a mundane and repetitive task for sysadmins and no one wants to do the same thing over and over again. For SRE organizations it becomes a priority to automate repetitive processes because it only creates high performing systems but also frees up time for a sysadmin to invest it on more beneficial work.
Automation and eliminating toil are closely related. When teams spend their time manually running production systems, they are investing a lot of their time in tasks that are automatable. A lot of areas can be identified where teams are investing their time in operational tasks that are not engineering focused. Focusing on reducing toil results in freed up time of various individuals and the operational costs can be reinvested in areas that can boost productivity.
