The latest News and Information on Service Reliability Engineering and related technologies.
Service level objectives (SLOs), and the subsequent service level indicators (SLIs) are the foundation to establishing a strong SRE culture and how they promote accountability, trust and timely innovation. We are on a mission to simplify SLO and Error Budget tracking and with that aim in mind, we have added the SLO Tracker feature to the Squadcast platform. SLO Tracker seeks to provide a simple and effective way to keep track of your error budget burn rate without the hassle of configuring and aggregating multiple data sources.
Site Reliability Engineers (SREs) have a considerable set of tasks to juggle no matter where they work or how long their company has had an SRE practice. But if you’re the very first SRE to join an organization – as many SREs are these days, given that the SRE trend is trickling down into smaller and smaller companies – you face a special group of challenges. You may find it difficult to get buy-in for SRE from other technical teams.
SLAs, SLOs and SLIs are fundamental to site reliability engineering (SRE), but what are they and why are they important for delivering services?
Any engineered system does not guarantee 100% uptime. There are bound to be some unforeseen system failures that cause downtime for the customers or create a poor customer experience. It is, therefore, best practice to take into account a margin for plausible failures. An error budget is this margin of error that the customer is informed about beforehand to secure tolerance during system failure for a decided number of hours.
A Service Level Agreement (SLA) consists of many service commitments. It is an essential part of a contract to outsource software development or software support between two or more parties, specifying the duties and the quality and type of service a company would provide for a fee to a customer.
