20 Minutes with Rob Meaney on Operability

If the SRE on-call team is in Delivery, they will be funded by a capex Delivery budget. In an SME or enterprise organisation with IT as a Cost Centre, You Build It SRE Run It is very different. There are segregated Delivery and Operations functions, due to COBIT and Plan-Build-Run. The SRE on-call team could be within the Delivery function, and report into the Head of Delivery.

• Furthermore, the user experience of application availability will be constrained by lower levels of user device availability.
• Another way to secure software is to use proper authentication and authorization procedures.
• We start any piece of work using a technique called user story mapping, as part of this process we invite Customer Support Engineers and Operations Engineers along.
• The Team Guide books are written and curated by experienced software practitioners and emphasise the need for collaboration and learning, with the team at the centre.
• The level of production support afforded to an application in You Build It You Run It at scale should be based on its availability target.

Each Delivery team is on L1 support for their applications, and creates their own monitoring dashboard and alerts. There should be a consistent toolchain for anomaly detection and alert notifications for all Delivery teams, that can incorporate those dashboards and alerts. A domain rota is a single Delivery team member on-call for a logical grouping of applications with an established affinity, from multiple Delivery teams.

Production support as revenue insurance

Not all of them would deliver primary value to users, so you need to be mindful of that. Lastly, I fostered a culture of sustainability operating back-end services that pays rich dividends. There were a bunch of cool technologies hiding behind our products, but we wanted to innovate and shape the future. A software program performs several automated steps to verify the operability of various components.

He counters this by arguing an SRE team is cheaper than an Operations team, as headcount is reduced by task automation. Recruitment challenges will be exacerbated by smaller budgets in IT as a Cost Centre organisations. The touted headcount benefit is absurd, as salary rates are invariably higher for developers than sysadmins. The ways in which to carry out the actual implementation and improvement of the operability of your software may depend on the effective capacity of the team.

Patterns for Performance and Operability: Building and Testing Enterprise Software

Strong build & release engineering capabilities are key to rapid and reliable delivery of modern software systems. Learn how software releasability means not only being able to deploy faster, but also being able to quickly recover from disaster and adapt to changing technical and business challenges. Learn practical insights on how testability can help bring teams together to observe, control and understand the systems they build. Enabling them to better meet customer needs, achieve a transparent level of quality and predictability of delivery.

You Build It You Run It has a higher degree of risk coverage, with no limits on deployment throughput and a short TTR to minimise revenue losses on failure. Production support should be thought of as a revenue insurance policy. As insurance policies, You Build It Ops Run It and You Build It You Run https://globalcloudteam.com/glossary/operability/ It are opposites at scale in terms of risk coverage and costs. It has a higher engineering cost than You Build It Ops Run It at scale, as the table stakes are higher. These include a centralised catalogue of service ownership, detailed runbooks, on-call training, and global operability measures.

Shipping Cloud-Native Software With a Focus on Sustainable Operability

An L2 Delivery team member will do best endeavours unpaid, and might be compensated per-callout with time off in lieu. Out of hours, higher availability applications are supported by their L1 Delivery teams. Lower availability applications are supported by the L1 Monitoring team, who will receive alerts and respond to incidents. When necessary, the Monitoring team will escalate to L2 Delivery team members on best endeavours. At first glance, it might make sense to pay a premium for a high-powered SRE team to support highly available services with critical levels of user traffic. However, investing in an SRE on-call team should be questioned when its applicability to IT as a Cost Centre is so challenging.

At 99.5%, the Delivery team is more cost effective at availability restoration of a 3 hour 36 minute outage than Application Operations. The Service Desk will receive customer requests, and Operations Bridge will monitor dashboards and receive alerts. Both L1 teams will be trained to resolve simple technology issues, and to escalate more complicated tickets to L2. Application Operations will respond to incidents that require technology specialisation, and when necessary will escalate to an L3 Delivery team to contribute their expertise to an incident. Lead times are minimised as there are no handoffs to the SRE on-call team. In IT as a Cost Centre, You Build It SRE Run It consists of single-level and multi-level support.

By using them correctly, you can ensure that your software is of high quality and safe from unauthorized access. Another way to secure software is to use proper authentication and authorization procedures. This ensures that only authorized users are able to access the software and its data.

With Application Operations responsible for production support, a Delivery team will be unaware of or uninvolved in production incidents. Application Operations cannot build operability into applications they do not own, and a Delivery team will have little reason to prioritise operational features. Error budgets are unlikely to magically solve the politics and bureaucracy that exists between Delivery teams and an SRE on-call team. Product managers, developers, and/or sysadmins might not agree on a service availability level, availability losses in recent incidents, and/or the remaining latitude in an error budget. A Head of Product might not accept an SRE block on deployments, when an error budget is lost.

Great DevOps Metrics — and How to Choose the Right Metrics

Heads of Product/Delivery/Operations might not accept an additional nine of reliability means an order of magnitude more engineering effort. The divide between Delivery and Operations teams is always the constraint in IT performance. SRE as a Cult refers https://globalcloudteam.com/ to the marketing of SRE teams, SRE certifications as a panacea for technology problems. In 2020, I learned of a sysadmin team that were rebranded as an SRE team, received a small pay increase… and then carried on doing the same sysadmin work.

As software engineers, we mainly talk about the power of tech skills and spending time learning new skills. However, there is also the influence that impacts your career as well. Your organization’s culture decides whether stakeholder management and positioning non-functional engineering work are going to be easy or challenging.

Continuous Delivery and Operability at scale

Information radiators help engineers, managers, and executives understand at a glance the progress being made and alignment with organisational goals. Transparency also reduces the potential for accidents and bad behaviours. As Louis Brandeis said in Other People’s Money “sunlight is said to be the best of disinfectants; electric light the most efficient policeman”. Reliability means balancing the risk of unavailability with the cost of sustaining availability. Delivery teams are empowered to test product hypotheses and deliver outcomes. If the review is successful, the development team shares the on-call rota with some SREs.
