TCA provides APIs to standardize natural language description of technology stack components, cluster a portfolio of technology stacks into similar technology stack groups, match technology stacks to docker, openshift or operator catalog images.
1. App1: rhel, db2, java, tomcat
2. App2: .net, java, oracle db
3. App3: dot net, java, oracle dbms
TCA takes the following steps to recommend the containerization.
Standardize: Standardize natural language inputs to relevant named entities of technology stacks present in our knowledge base. For details on the knowledge base please check the db folder. For example, the inputs in App1,App2,App3 get mapped as the following named entities.
1. App1: rhel: RedHat Enterprise Linux, db2: DB2, java: Java, tomcat: Apache Tomcat
2. App2: .net: .NET, java: Java, oracle db: Oracle DB
3. App3: dot net: .NET, java: Java, oracle dbms: Oracle DB
Clustering: Cluster the standardized technology stack components into groups of similar technology stacks. For example, the standardized technology stacks for App1,App2,App3 get clustered into the two technology stack clusters.
1. Cluster1: {App1}
2. Cluster2: {App2, App3}
Containerize: Determines whether a technology stack is fully containerizable, partially containerizable or not containerizableat all. If a technology stack is recommended as fully or partially containerizable, it also generates container images based on DockerHub or Openshift image catalogs. It is also possible to provide custom user-defined catalogs for matching to catalog images. For example, if a user decides to generate DockerHub related images, then TCA generates the following images.
1. Cluster1: tomcat|https://hub.docker.com/_/tomcats
2. Cluster2: db2|https://hub.docker.com/r/ibmcom/db2
For OpenShift, TCA generates the following images.
1. Cluster1: tomcat|https://access.redhat.com/containers/#/registry.access.redhat.com/jboss-webserver-3/webserver31-tomcat8-openshift
2. Cluster2: db2|https://access.redhat.com/containers/#/cp.stg.icr.io/cp/ftm/base/ftm-db2-base
The pipeline ingests raw inputs from clients data and standardizes the data to generate named entities and versions. For standardizing or normalizing raw inputs we use a tf-idf similarity based approach. To find container images we represent images in terms of named entities as well. The normalized representation helps to match legacy applications with container images to suggest the best possible recommendations.
