Harness Service Reliability Management vs Blameless

Summary:

Harness and Blameless both provide SLO management capabilities. Harness Service Reliability Management (SRM) is a SLO management module that is part of a larger software delivery (CI/CD) platform. Harness SRM is designed to facilitate greater collaboration between SREs and Developers while also automating many actions related to SLO management like governing software deployments.

Blameless provides SLO management capabilities as part of a larger SRE-centric platform. Blamless not provide SLO-based automation across the software delivery lifecycle as evident in the following analysis.

SaaS & On-Premises:

Harness SRM is available as either SaaS or self-managed software that can be deployed anywhere.

Blameless is available via SaaS only.

Custom Reliability Policies:

Harness SRM contains a built in policy engine based on Open Policy Agent (OPA). This enables Harness users to define and enforce custom policies with via UI or via policy-as-code. Policies within Harness can be used to send notifications or to actively manage software delivery pipelines via reliability guardrails.

Blameless offers the ability to create policies for notification purposes only.

Reliability Guardrails integrated with CI/CD pipelines:

Harness SRM reliability guardrail policies are used to automatically determine if deployment pipelines should proceed or stop given the status of SLOs an Error Budgets. This makes it possible to effectively standardize and scale the management of pipelines via SLO management processes.

Blameless does not offer this capability.

Service Health Indicators:

Harness SRM can determine and display the health of application services using SLOs and/or metrics to derive the overall health. By using a combination of SLOs and metrics, Harness can provide a more precise calculation of service health.

Blameless can determine and display the health of application services using SLOs only.

Service Reliability Checks:

Harness SRM can determine the health of services across all stages of software delivery by using a combination of AI/ML techniques on logs and metrics and through error tracking. These capabilities make it possible for developers to proactively improve the quality and reliability of their application services before deploying to production.

Blameless does not offer service reliability checks.

Automated Deployment Verification and Rollback (Continuous Verification):

Continuous Verification is the process of monitoring your app for abnormalities after a deployment. For example, Continuous Verification could catch a latency issue or 5xx errors and automatically roll back your app to the previous version. The idea is to catch errors as quickly as possible – ideally, before customers notice – and make a seamless transition back to the prior version.

Harness provides Continuous Verification out of the box, effectively reducing risk and reputational damage from downtime. Harness supports many vendors, including Prometheus, Datadog, AppDynamics, New Relic, StackDriver, CloudWatch, and custom monitoring and observability tools.

Blameless does not offer this capability.

Error Tracking:

Harness SRM is capable of detecting all run-time exceptions within Java applications and providing detailed debugging information so that developers can resolve problematic exceptions before they deploy to production. This improves the quality of software which also improves reliability over time.

Blameless does not offer error tracking capabilities.

Fine-Grained Role-Based Access Control:

Harness enables full customization of role based access controls (RBAC) with the SRM module and across the larger platform. Harness RBAC was built to offer the ultimate in flexibility as required by the largest enterprises.

Blameless offers 3 roles (admin, reader, writer) with a total of 3 rules (read, create, execute) available for SLO management.

Unified Software Delivery Platform:

Harness SRM is the SLO management module of the Harness Software Delivery Platform. Each module can be used standalone (integrated as a best of breed solution to a DevOps toolchain) or as part of the platform. When used as part of the platform, each module passes meta-data and can provide greater levels of automation than if used standalone.

Blameless does not offer a unified software delivery platform.
