SLA Error Budget Calculator

SLAError Budget Calculator

This tool will help you to meet your SLA requirements and manage the risk. It is used to measure how much risk we are willing to tolerate in a service. Calculate the tolerable downtime of your service. 

How to use the SLA & Uptime Calculator?

1. Enter the Measured Availability of your server in the input box
2. Enter the SLA/SLO Threshold of your server in the input box
3. Click on the 'Calculate' button to view the respective error budget time.

What is an SLA? 

The degree of service that a client anticipates from a provider is outlined in a service-level agreement (SLA). The agreed-upon service levels are specified in SLAs. The metrics used to measure that specific service, and the sanctions and remedies applied if they are not reached. SLAs can exist between businesses and outside suppliers or between two sections of the same company. You can start SLA monitoring only when both parties have signed the SLA.

What is an Error Budget?

A methodology for controlling risk and achieving harmony between development and SREs is called an error budget. They are primarily used to gauge the level of risk we are willing to accept in a service. An error budget is still available if the measured uptime/availability is higher than the SLA/SLO. Consequently, the production can be pushed for new features and releases.

Error Budgets and Risks

We use an error budget to move quickly without sacrificing high dependability while aiming for perfection. You would think that site reliability engineers want to create impenetrable systems, and that ignores the fact that achieving 100% reliability is rarely the objective. Instead, it is our responsibility to weigh the many other objectives for our services against reliability.

SREs aspire to offer excellent customer and end-user service while having the freedom to make quick and frequent system changes. By providing as little excess as necessary to provide quality service, we aim to ensure that the queries and the income keep flowing. Error budgets are helpful because they allow us to quantify tradeoffs while using an engineering strategy to achieve these goals. Your error budget, which is the headroom above your SLA, serves as a risk indicator. One of the best tools SRE has to achieve the different competing aims that services on the internet are to manage and use this error budget wisely.
