Cloud Options 101: Cloud, Hybrid Cloud, SaaS, or PaaS?

Cloud Options 101:
Cloud, Hybrid Cloud, SaaS, or PaaS?

 

There are a lot of options these days for cloud offerings.

If you are looking for a deep dive into the complexities underneath the covers, this document might be a bit too 101 level for you. We’ll discuss here at a high level, some of the different terms used to discuss cloud options, and some of the major players as well.

Cloud

Simply put, the old joke goes “there is no cloud, there’s just somebody else’s computer”; this is pretty accurate, really.

This is more of a marketing term than a hard definition. Cloud refers to someone else’s data center, usually (more to come on this…); where usually some level of virtualization is in play. By some level, I refer to the many layers of virtualization in use today: from hardware, to OS, to network and storage, and I/O.
To back up a minute, a data center I will assume is a construct we all understand. Basically it’s an empty building with power, climate control, and high speed (hopefully) redundant internet feeds into which companies (or a single company) puts their servers and storage.
Most of the websites we know and love, live in someones data center, somewhere. Space in a data center can be rented out to store YOUR systems, that you move there, or ‘bare metal’ servers onto which you load whatever you like. Or, as we will discuss, the operator or Cloud Services Provider (CSP) may have a proprietary layer, or a ‘platform’ they offer to run certain types of applications.
So if you have an application, and want to run it somewhere else, not on site, that’s moving to the cloud, no matter the vagaries or the options used.

Hybrid Cloud

Hybrid Cloud is a mixed solution; mixed, in that it means there is some software that still runs on premise, and some that runs in the cloud.
Hybrid: This doesn’t mean necessarily splitting applications, though sometimes that is done, this is just a general term referring to a situation where not everything is moved to the cloud.

SaaS: Software as a Service

SaaS, or Software as a Service, is where one accesses a ‘canned’ software product that just simply runs in the cloud, and is delivered via browser. The most obvious example of this is Salesforce.com, though there are countless others.

PaaS: Platform as a Service

Finally, we have PaaS, or Platform as a Service.
While a little more involved than other cloud options, there are CSPs that offer platforms for .net applications, Linux applications, specialized IBM centric applications requiring DB2, WebSphere, and more. The licensing for the application subsystems (database, OS, web app servers, etc.) is included in the base metered price.

Upgrading For Federal Reserve Bank MQ Integration

For financial institutions using WebSphere MQ V6.x or older to communicate with the Federal Reserve Bank, your time is running out… and fast. WebSphere MQ V6.x went End of Support on September 30th, 2012 and the Federal Reserve Bank is requiring upgrades to a current, supported version.

WebSphere MQ V7.0.0 and V7.0.1 went End of Support at the end of September 2015. For those of you wondering about WebSphere MQ V7.1, you might want to reconsider. While still technically supported by IBM, V7.1 is likely looking at another upgrade within the next 18 to 24 months.
From a business perspective, I recommend financial institutions upgrade to IBM MQ V8.x. At the very least, you could consider MQ V7.5.x.

IBM MQ V8.x, rebranded from WebSphere MQ is now full equipped with fix pack 3 and has proven to be very stable.

Further, MQ V7.5.0.5 and MQ V8.0.0.3, have deprecated SSLv3 connections due to the Poodle Exploit and reduced the number of supported Cipher Suites. (It is critical you understand the supported connection protocols and Cipher Suites supported by the Federal Reserve Bank.)
But MQ upgrades are only half the story.

If you haven’t been keeping pace with MQ updates, you’ve likely not been keeping pace with OS either. OS updates to supported versions are arguably equally as critical as MQ.
