This topic describes the lifecycle management of Hologres, including the runtime lifecycle policy (RLP), the version discontinuation policy, Hologres versions, and the dates of the general availability (GA) and end of service (EOS) milestones for each version.

Background information

Product and service upgrades and phase-outs are universal in the software industry. So is Hologres. As Alibaba Cloud constantly optimizes Hologres, the features and architectures provided by Hologres become more diversified, powerful, and user-friendly. However, an earlier Hologres version may fail to meet specific business requirements. The service performance, such as the stability, usability, and compatibility, may also be affected as time passes. Therefore, new Hologres versions are a must to provide you with high-quality services. Regular upgrades and lifecycle management of Hologres help you master up-to-date technologies that empower your business. Before a new Hologres version is released, factors such as the business migration, upgrade costs, service stability, and long-term IT planning are all considered. To provide you with enterprise-level service capabilities and information about service evolution, Hologres adopts a lifecycle management system that specifies the RLP and version discontinuation policy. The following sections provide detailed information about Hologres lifecycle management. You can read these sections to get prepared for regular upgrades of Hologres.

RLP

RLP regulates the specifications for lifecycle management of a Hologres version from the time when the version is released to the time when the version is discontinued. The following figure shows the lifecycle of a Hologres version. RLP
Milestone Full name Description Time point Remarks

EOS End of service A Hologres version is discontinued. Two years after Month T After the EOS date of a Hologres version, the version is no longer updated and no more new minor versions are provided.
Note After the EOS date of a Hologres version, technical support for this version, such as Q&A, problem resolving, and Service Level Agreement (SLA)-based compensation management, is no longer provided.
Note
  • You will be notified of the GA or EOS date at least three months before a Hologres version is released or discontinued. The Hologres version will not be released or discontinued at a time point before the notified date.
  • If a serious defect is found in a Hologres version, the Hologres team will control the version to fix the defect and release a new compatible version as soon as possible. This helps prevent risks such as security problems or data inaccuracy caused by the defect.
