SRE has a particular approach towards IT functions for the contemporary, bigger-scale, cloud-native software systems and delivery, in comparison to the traditional IT functions that aren’t executing at that rapidity. That’s the reason new approaches with SRE are advancing a great grip across the IT industries. SRE model frames strong, fruitful interactions between the SRE teams and developments utilizing the SLOs, SLIs, and error budgets to stabilize the speed of fresh features of whichever work is required to make the software reliable.
Mentioned here are the best ways your larger enterprises can take quick benefits of SRE and what are the effects SRE has on the IT functions for leaders as well as hands-on managers!
- Allow software engineers design IT Operation
People in the SRE teams are either the software developers with good operations knowhow or the IT functional people with proper software development skills. Both ways, software engineering is the vital approach that SRE teams use for solving issues. Also, this software engineering approach makes an extension of the role of the development team from time to time. In case the SRE team which is looking after a specific service or application finds out that it is occupying more than 50 percent of its major time executing manual work (TOIL) to address the problems, software solutions need to be looked and implemented in form of automation, process improvement, etc., which will require the involvement of development teams.
The development team must pick up the functional tasks and assist them to fix it effortlessly; where required they can learn about the functional features too and implement accordingly. Thus, it is known to be a very disciplined balance that stands between inclining on the SRE engineers’ skill-sets, at the same time maintaining accountability for the functions of the software in the development team.
- Treat IT Operations as a value creation center
SRE is generally a higher skill activity, that’s why it demands to select experienced, highly-skilled, and committed staffs who know to easily automate their way out from mundane activities. Enterprises who accept SRE thus require to stop indulging IT operations as a line item subject towards cost center droppings. In its place, they must ensure to treat the IT operations as a value center that can assist the organization to evade downtime and make the best use of revenue and service accessibility.
According to Jaana B. Dogan, SRE at Google, “Downscale the SRE support if your project is shrinking in scale, and finally let your development team own the SRE work if the scale doesn’t require SRE support.”
Thus, the enterprises can hold a smaller SRE track for crucial services, while leaving the IT functions of less proved services and the smaller ones to the development teams who are finely placed to provide support to the services they are developing as they are knowledgeable about it.
- Focus on error budget and SLOs rigorously
SLO stays at the core of the SRE approach for the service or application which is being tracked by the SRE team. The SRE along with product owner for its service must select suitable SLOs and related Error budget which provides them with a sufficient margin of possible interruption to cover unpredicted problems whereas delivering aspects and updates at a rate which the users anticipate. The SRE along with the Product Owner can decide on stopping new releases when there is a chance of error budget breach and also use up all the error budget, thus maintaining a balance between stability and speed.
The approach of SLO, SLI, and Error Budget even drives the approval of synthetic operation monitoring, a superb practice for the customer-facing structures which assesses whole customer journeys daily from an automatic script. This successively carries the service much closer to the customers and at the same time, the developers and the SRE teams come closer to the customers also.
- Allow SRE kickstart cloud-native IT Ops
SRE sets forth an accurate, particular set of tools and practices and team dynamism that works for bigger companies. Those who work in an enterprise who require moving swiftly to cloud-native IT operations from a traditional setup, they are recommended to adopt SRE properly which works here well.
Damien Daly, CTO at Glofox, Ireland, enlightened, “As we are getting bigger, concentrating our platform development and reliability expertise in SRE will allow us to more effectively develop both. Reliability and our platform are first-class concerns and need to be treated with the respect they deserve.”
Well, you might also avoid a few of the organizational clumsiness of other distinct delivery models by adopting SRE effortlessly.
- Make use of managed services to adopt SRE quickly
One good way to acquire the profits of SRE discipline swiftly, sans hiring many of expensive SRE employees, is to make use of an external provider for SRE. There have been few evolving SRE-as-service contributions from proficient outsourced manages service providers. With many distinct features of SRE dynamics involved, then SRE in the form of service can execute greatly.
Another feature of accomplishment with managed SRE is the practice of tooling to describe and automate the standardized functioning processes required to maintain the software running properly in the production.
“Standardizing procedures helps SREs save time, reduces errors (especially under pressure or when a procedure is crucial but run infrequently), and makes it easier to spot anomalies (the outcome is different than expected),” as per DevOps luminary Damon Edwards, co-founder of Rundeck, who stated this in a blog post on Operations as a Service.
While implementing a managed SRE approach, you should anticipate investing more time to design and develop standardized operating processes by utilizing a software tool that is shared along with a managed SRE partner.
Get going with SRE
By now you might have understood how SRE works remarkably in modern age IT operations and learned the efficient ways your bigger enterprises can benefit by taking the help of SRE teams using SLOs and error budgets, and the effect that has on IT operations! Hence, get started with SRE now in your IT operations.
