Then map to a pattern that minimizes refactor while maximizing operational gain.<\/p>\n<h3>Modern stateless web app<\/h3>\n<p>Recommended: Functions + API Gateway + OCIR; choose OKE if the app needs complex networking or long\u2011running processes. This is fastest to market and cost\u2011efficient for spiky traffic because you only pay for active execution.<\/p>\n<h3>Microservices at scale<\/h3>\n<p>Recommended: OKE + OCIR + Load Balancer + Autonomous Database for persistent state. Kubernetes gives you service mesh capabilities and predictable scaling for many services; pair with observability for tracing.<\/p>\n<h3>APIs &#038; enterprise integration<\/h3>\n<p>Recommended: Oracle Integration Cloud + API Platform + GoldenGate (for CDC). Use OIC\u2019s connectors to reduce custom glue code and GoldenGate to keep source systems synchronised in near real time. See our guide to <a href=\"https:\/\/cloudshinepro.com\/system-integration-flows-best-practices-and-techniques\/\" target=\"_blank\">system integration flows<\/a> for patterns and best practices when designing integrations at enterprise scale.<\/p>\n<h3>Analytics \/ data warehouse<\/h3>\n<p>Recommended: ADW + Analytics Cloud + Data Flow. This stack removes cluster ops and speeds ML data prep and reporting cycles.<\/p>\n<h3>Legacy 3\u2011tier ERP \/ on\u2011prem DB<\/h3>\n<p>Recommended initial move: lift to Compute or OKE for fast migration, then plan a phased refactor toward Autonomous Database and OIC for long\u2011term OPEX benefits.

Use it to speed delivery and reduce ops for modern apps; choose IaaS for legacy or when OS\u2011level control is mandatory.<\/p>\n<h4>Can I move an on\u2011prem Oracle DB to Autonomous Database with zero downtime?<\/h4>\n<p>Yes\u2014zero downtime migrations are possible using GoldenGate CDC with a tested cutover plan, but you should validate in a PoC and reserve a short migration window for the final sync.<\/p>\n<h4>How do I choose between OKE and Functions?<\/h4>\n<p>Pick OKE for long\u2011running microservices and complex container orchestration; choose Functions for event\u2011driven, short\u2011lived tasks with minimal operational overhead.<\/p>\n<h4>Where do I find OCI PaaS pricing and a cost estimator?<\/h4>\n<p>Use Oracle\u2019s official Cost Estimator and the <a href=\"https:\/\/www.oracle.com\/cloud\/price-list\/\" target=\"_blank\" rel=\"nofollow\">service price lists<\/a> to model OCPU hours, function invocations, integration message rates and storage.<\/p>\n<p><strong>Key takeaway:<\/strong> Start with a focused PoC, protect cost and security guardrails, and migrate incrementally from IaaS to PaaS where it delivers the most operational value. When you need hands\u2011on validation or team upskilling, consider CloudShine\u2019s migration workshops or a week\u2011long sprint to make the move predictable and teach your operators how to run it in production.<\/p>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"Article\",\n  \"datePublished\": \"2026-03-21T11:00:35.650Z\",\n  \"dateModified\": \"2026-03-21T11:00:35.658Z\",\n  \"headline\": \"OCI PaaS Playbook \u2014 Services, Costs & Migration Tips\",\n  \"description\": \"Practical OCI PaaS playbook: compare Oracle Cloud PaaS services, choose the right option, and follow a step\u2011by\u2011step migration, cost & security checklist.
