PaaS is a category of cloud computing service providing platform and solution stack. This service model is including not only computing infrastructure (IaaS), but also application design, development, testing, team collaboration, integration features, database integration, scalability, security and others. In addition to that, it might provide service management capabilities such as monitoring, workflow management, etc.
As cloud market becomes mature, IT, customers and application development are looking into complete solutions. All PLM vendors are in full swing into IaaS cloud PLM option. Cloud PLM experience brings the need to dig more into nuts and bolts of cloud business. It includes understanding of cost, scale, service maintenance, application development, partnership. So, fundamental question many vendors and customers have is what is the best way to make cloud PLM efficient? Understanding of PaaS option is an important step. I shared some of my thoughts about PaaS and PLM before- Cloud PLM and PaaS dilemma, Will cloud PLM develop PaaS options?
My blogging buddy and well known PLM analyst Chad Jackson tweetstormed what he learned at Siemens PLM about furure TeamCenter platform development. While I’m still waiting for full blog post on Chad’s Lifecycle Insight, the following filtered tweetstorm can give some idea about Siemens PLM platform strategy:
It resonated with my previous thoughts about cloud PLM and PaaS and made me think why Siemens PLM as well as any other PLM vendor can consider PaaS as a right option for their cloud PLM strategy. Here are my 3 reasons to develop PLM PaaS:
1- Agile development.
Vendors should be able to go fast in the development of applications, ability to customize existing features and supporting new opportunities. Businesses are much more dynamic these days. Everyone wants to be agile. PLM vendors too. So, to get up to speed with business, PLM vendors need to have a stable platform to build on. PLM PaaS can be one.
2- Better upgrade strategies
Let’s take marketing gloves off. Regardless on deployment options (on premise; private cloud; public cloud), you need to deal with upgrades. Databases, services, data model changes- this is only a very short list. PaaS can hide upgrades from customer and application developers by providing a stable platform layer. This layer requires less frequent upgrades.
3- Scaling factor and cost.
Cost is important. Cloud is not cheap as many of us thoughts from the beginning. Customers are demanding new business models and optimized cost. The development and customization cost is another problem. Scaling and keeping cost low is also huge challenge. Utilization of enterprise servers is still relatively low. PaaS can answer on the question how to share resources and scale with low cost.
What is my conclusion? Most of PLM vendors took IaaS option as a starting point to develop cloud business. It is okay and will provide important experience from different perspective – technologies, business, user interface. However, IaaS won’t remove fundamental enterprise PLM issues – implementation complexity, upgrade challenges, high diversity of requirements and business changes. PaaS option can become the next logical step to optimize platform and application for agile delivery. It looks like Siemens is making steps towards this direction. Just my thoughts…
