Storage, compute, and networking will continue to evolve and so is the cloud offerings from various vendorsearly making large investments feel in terms of lost opportunity or unrealized expectations.While Cloud being the foundation for digital transformation means that Cloud itself is a platform of reusabil-ity and open standards and needs to be viewed differently from traditional datacenter. Any move to cloud where applications are designed as mono-lithic and tightly coupled with Cloud itself will take us back to where we are today with very short-term bene-fits. Hence the move should be driv-en by decomposing the application into micro services deployed to plat-form implementation decoupling the same from any vendor platform de-pendency or infrastructure making it more fluid.Evolution of opensource is driving affordability, transparency, perpetuity, interoperability and flexibility across all stacks of IT. It is so pervasive and hence easy to forget how much is in the stack. Opensource is also empowering the developer community beyond con-trolling the application code to com-pletely codify the infrastructure, shap-ing product and user experience. The real cloud can only be achieved with opensource as the future is moving away from monolithic applications to a decomposed model with ability to scale, portable, interoperable and with extreme automation across all layers leading to the notion of "NoOps". Moving to Cloud without adaptive cloud architecture renders the cloud immaterial. Storage, compute, and net-working will continue to evolve and so is the cloud offerings from various vendors. While IaaS can be the short-term option the core focus for enter-prises must be to leverage the PaaS offerings. SaaS being strictly vendor based will remain at the edges. Pro-prietary / customized PaaS should be the way forward for large enterprises and vendor owned open source PaaS can be an alternate for other scenarios. Adopting open source technologies, Open Cloud, and other emerging tech-nologies is part of a shift of putting business needs first and building back-wards to the technical implementation and make IT relevant.
