Why PaaS might be the better choice when selecting a flavour of Optimizely CMS

Choosing the right CMS platform in today's rapidly evolving digital landscape hinges on flexibility, security, and scalability. In the world of DXP/Enterprise CMS, Optimizely’s Platform as a Service (PaaS) offers a robust solution and has been a great solution, but with the introduction of Optimizely CMS SaaS Core, is PaaS still the best option? For enterprise... probably.

Comprehensive Capabilities of Optimizely CMS PaaS

Optimizely CMS PaaS matches and surpasses the functionalities of its SaaS counterpart, offering an environment ripe for deep customization, integration, and secure, scalable growth:

  • Complete Customisation and Integration: With Optimizely CMS PaaS, businesses can tailor their CMS to specific integrations with existing systems, a level of customisation that is not always feasible in the SaaS offering.

  • Advanced Security and Compliance: Optimizely CMS PaaS Core provides greater choice when it comes to authentication, as along with the "standard" providers.

  • Unmatched Scalability: Designed to support high traffic and complex data interactions, Optimizely PaaS CMS ensures that businesses can scale their operations confidently.

With the PaaS as SaaS solution you can run both your main site within the DXP hosted instance and also any satellite sites on external hosting.

The Versatility of a Hybrid Approach

Optimizely CMS PaaS does not just excel in traditional PaaS environments but also supports a hybrid approach, by installing and setting up Optimizely Graph and using this for simple satellite that can be built out in Node, React, etc. This flexibility allows businesses to adapt their digital strategy to meet specific needs without compromising on the power and security offered by the PaaS solution.

Is Optimizely CMS PaaS the Preferred Choice?

As always, it depends. Optimizely CMS PaaS excels in meeting complex enterprise needs through its robust support across varied deployment scenarios. It combines the agility of SaaS with the robustness of PaaS, offering a versatile and powerful CMS platform that stands out in the market.

It's vital to select a platform based on specific needs rather than market buzz. PaaS offers the flexibility to incorporate custom APIs and backend layers without involving additional tech vendors. If your requirements are more aligned with using segregated services or different tech stacks, then the SaaS model might be more appropriate.


In conclusion, a thorough CMS selection process that assesses each use case is key. While Optimizely's PaaS solution is powerful for specific needs, the agility of a SaaS model might be the ideal solution, especially within a best-of-breed strategy where selecting the top systems for each function is crucial. SaaS can seamlessly integrate into this approach, offering simplicity and efficiency critical for optimal performance.

Edit: It has been confirmed that once in GA, the SaaS offering will have three environments, the same as the PaaS offering
