Public Cloud, co-location and managed services ... what is the cloud?

Recently I have had conversation with a number of people that are selling and implementing 'cloud' solutions. I put cloud in quotes as implementations like co-location (aka co-lo) and managed services (sometimes referred to as 'your mess for less') have become popular options for companies moving to the cloud. These are obviously not pure public cloud offerings and probably more of hybrid cloud implementations as the infrastructure (PasS and IaaS)is dedicated to a specific customer. This eliminates the security, multi-tenancy, performance and other concerns that companies have regarding public cloud.

Are co-location and managed services cloud to you? Are they something your company is considering when you think about cloud ?

What is SOA ?

First, let’s mention what SOA is not:
• SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications.
• SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place.
• The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

Bringing Cloud 1.0 in house - Is moving to private cloud from the public cloud already happening ?

Visiting with a major corporation that is bringing all their managed services in house. Granted, most of the infrastructure is on cloud 1.0 (the mainframe), but is this something we will see with cloud 2.0 a few years from now? Certainly, the reasons the company is doing this - lack of innovation, not having easy access to data that belongs to them, being held hostage to the business and technical models of the service provider, and raising costs because the vendor feels the customer is stuck with them - are all items that folks are not hearing are things to beware when moving to SaaS or public cloud DaaS. Could be something to watch.

Migrating integration to the cloud

There are many components of your IT infrastructure that can be deployed to the cloud. The most well-known option is to run your applications in the cloud using Software-as-a-Service. It is also possible to run your database systems in the cloud using Database-as-a-Service (Daas). It is even possible to run your entire IT software and hardware infrastructure in the cloud using Platform-as-a-Service (PaaS). So, why not run your integration architecture in the cloud? It is possible and called Integration-as-a-Service (IaaS). Integration-as-a-Service (IaaS) is not to be confused with Infrastructure-as-a-Service (also IaaS). Infrastructure-as-a-Service is running your hardware infrastructure in the cloud. I will explore this hot new cloud migration area in my next few blogs.
