Cloud-Application-Cloud-Readiness-Check-List
Introduction
The purpose of this document is to define and describe the standards that are required from any modernized application that about to on-board to SaaS.
Modernized Applications
Any product/Application that developed for SaaS only and desired to be at some level of Dev/Ops and continuously delivery approach
| Cloud Readiness | Description | |
|---|---|---|
| Saleable | - Complete product definition in Control Tower with SKUs clearly defined - Complete license generation strategy |
|
| Deployability Configurability | Cloud Deployment & Configuration | - Cloud Applications can be deployed on a given Cloud platform in a fully or partially automated manner. - All required feature and functional configuration management should be provided through a Web/API enabled interface. Like enable tenant capabilities |
| Availability | HA & Self Recovery | - HA, Load Balancing and Fault Tolerance testing - App recover automatically after machine restart in order to maintain stability - Restarting App service will restore all node functionality and integrations - DB/File System connection should restore automatically after an issue (ex, network connectivity) without restarting the App service and should document the problem in the logs. |
| Maintainability | Upgrade/Patch | - Cloud application component to be upgraded, patched or functions changed in a standard and predictable manner. Maintainability requires backward compatibility through 2 or more releases to enable maintenance activities to occur online. |
| Recoverability | Backup & Restore | - Cloud Application has a complete data backup and recovery solution with well-documented backup and recovery procedures that have been validated and tested |
| Observability | Monitoring | - Expose application health for monitoring - node\component\farm\tenant\integration - Implement application monitoring and thresholds based on best practices - Major functionality monitoring (APM/BPM) for SLA calculation - Implement usage\load\performance monitoring on farm\components based on best practices - Runbooks – resolutions for each alert that will be handled by the NOC/Ops |
| Documentation | - SaaS Customer facing documentation portal - Internal documentations for Ops like deployment guide, upgrade, sizing guide, backend integration, APIs, affected functionality in case of a component failure, troubleshooting guide etc. | |
| Observability | Performance & Capacity | - Measure performance and load and share metrics - number of users\transactions\requests the farm can handle - Measure and determine farm capacity in term of number of tenants and their footprint - Provide runbook in case farm limit reached its threshold (Example - Add another Server) - Expose metrics of customer product usage - Can be implemented with the help of Tableau\Power BI reporting based on what expose. Like License usage, tenant information etc. |
| Securability Defensibility | Security | - Capability and awareness of the application to defend itself against incorrect usage. Both accidental and purposeful. Like develop WAF rules to protect Cloud Applications |
| Service Management | - Define what services from the customer's perspective will need to be fulfilled by the SaaS Ops team when the product goes live. A detailed service catalog needs to be listed as well as an instruction document of the services to be completed - Customer-oriented service catalogs need to be defined as corresponding service offerings and made available to customers through support tooling. The service offering requires a complete definition of the scope of the service and the information, documentation, etc. that needs to be provided. |
