Embedded database as a microservice for distributed container cloud platform

One or more non-transitory computer-readable media having stored thereon program code,

• the program code executable by a computing system providing a data center comprising:
• a plurality of hosts hosting a plurality of application images, respective application images being stored in a corresponding stored container that is instantiated when a requested application image is requested for a data center job;
• a plurality of container cloud managers on respective manager hosts, wherein the plurality of container cloud managers maintain respective instances of a master database, the master database instances comprising application image information, host information, and container information, wherein the container cloud managers manage resources of the data center;
• a replication manager, wherein the replication manager replicates database data from the master database instance of a master container cloud manager, corresponding to a first container cloud manager of the plurality of container cloud managers, to the master database instance of at least a first replication container cloud manager, corresponding to a second container cloud manager of the plurality of container cloud managers, the replicated database data comprising the application image information, the host information, and the container information;
• and
• a job scheduler, wherein the job scheduler and a container cloud manager of the plurality of container cloud managers form a job management platform of the data center;
• the program code being executable to cause the computing system to perform operations comprising:
• replicating database data from the master database instance of the master container cloud manager to the master database instance of the replication container cloud manager;
• receiving a request to generate an application image of a first application;
• building the application image of the first application and storing the application image in a container;
• storing a copy of the application image and the container on a first number of hosts of the plurality of hosts, wherein the first number of hosts are automatically selected by the container cloud manager of the plurality of container cloud managers based on resource load balance of the data center;
• subsequent to the storing the copy of the application image on the first number of hosts of the plurality of hosts, receiving a request to initiate a first job on a selected copy of the application image on a host of the first number of hosts;
• starting the container of the requested application image;
• starting the application of the requested application image;
• and
• starting the requested first job on the application and on the host of the first number of hosts.

A system for managing a data center comprising:

• a plurality of hosts for hosting a plurality of application images for one or more applications, respective application images being stored in a corresponding stored container that is instantiated when a requested application image is requested for a data center job;
• a container cloud manager on a manager host of the data center, wherein the container cloud manager manages resources of the data center and comprises a database;
• a replication manager, wherein the replication manager replicates database data from the master database instance of a master container cloud manager, corresponding to a first container cloud manager of the plurality of container cloud managers, to the master database instance of at least a first replication container cloud manager, corresponding to a second container cloud manager of the plurality of container cloud managers, the replicated database data comprising the application image information, the host information, and the container information;
• a job scheduler, wherein the job scheduler and container cloud manager form a job management platform of the data center, wherein the job management platform manages jobs running in containers in the data center;
• at least one processor;
• and
• one or more memories in communication with the at least one processor and storing computer-executable instructions, that when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• replicating database data from the master database instance of the master container cloud manager to the master database instance of the replication container cloud manager;
• receiving a request to generate an application image of a first application of the one or more applications;
• building the application image of the first application and storing the application image in a container;
• storing a copy of the application image and the container on a first number of hosts of the plurality of hosts, wherein the first number of hosts are automatically selected by the container cloud manager of the plurality of container cloud managers based on resource load balance of the data center;
• assigning a time to live value to at least a first copy of the application image and the container;
• subsequent to the storing the copy of the application image on the first number of hosts of the plurality of hosts, receiving a request to initiate a first job on a selected at least a second copy of the application image on a host of the first number of hosts;
• starting the container of the selected copy of the requested application image;
• starting the application of the selected copy of the requested application image;
• starting the requested first job on the application and on the host of the first number of hosts;
• determining that the time to live value has been exceeded;
• and
• deleting the first copy of the application image and the container.
