Cloud Computing Map of The World
2121/020202/20102010The Cloud Computing Definition We Use
1919/020202/20102010When we talk about Cloud Computing in CloudSplit this is what we mean:
· Virtualization: All the components in the system are configured in software and have APIs to allow access. The people component has essential been eliminated. People still exist but a Cloud Computing consumer never sees them. Instead they see an API or a web-page interface to all their services.
· Fine Grained Allocation: In Cloud Computing the units of allocation are small enough to make sense to even one-man businesses. Sub-cent pricing for transactions and zero upfront costs can make Cloud Computing very attractive for high growth start-ups and/or cost constrained IT departments.
· Bi-Directional Scalability: The ability to turn stuff off as fast as you can turn it on without incurring setup fees, extended contracts and/or waiting periods. This scale up/scale down model ideally suits spiky or seasonal workloads (e.g. the storage requirements of a University are significantly reduced out of term).
· All You Can Eat: The ability to consume resources in an unbounded fashion. Amazon will never tell you they are out of disk space. One of the trickiest problems to deal with prior to cloud computing was what to do when you hit your existing resource limitations (particularly disk space).
· Pay as You Use: Only pay for use, not configuration. If you do not turn on the node or store data, then you do not incur costs. Setup fees become a thing of the past.
Some Cool API Developments in the Cloud
2727/010101/20102010There are three API standards I am aware off that are seeking the holy grail of homogeneous access to heterogeneous clouds.
The ones to keep an eye on are:
- DeltaCloud : An initiative from RedHat. This a a generic RESTFul service that mediates access to the Amazon EC2, RedHat Enterprise Virtaulization Manager (RHEVM) and Rackspace (though its not clear whether slicehost.com is supported. Its targetted at spinning up compute nodes so there doesn’t seem to be a storage, queueing or entity store API yet.
- LibCloud was originally developed by the guys at CloudKick but it has recently been promoted to an Apache incubator project. Its a Python library which is again focussed on compute server management. It supports a lot more providers including Amazon Ec2, Slicehost, Rackspace, Linode, VPS.net, RimuHosting, GoGrid, Terremark and VCloud (phew!).
- SimpleCloud is an mega corp initiative by the big boys (Microsoft, IBM, Zend) and is focussed on enabling cloud APIs in the PHP space. The website talks about blob storage queuing and structured storage (what SimpleCloud call document storage, which makes no sense to me). However the download they supply only supports the storage API at the moment. Surprisingly they have no support for managing compute instances. The APIs supported for blob storage right now are Microsoft Azure, Amazon, Nirvanix and local storage.
Gartner : Virtualisation No 1, Cloud Computing No 2 for CIOs in 2010
2020/010101/20102010Gartner states that CIO’s place virtualisation and cloud computing in the 1 and 2 spot in the annual Gartner CIO survey for 2010.
Let me paraphrase that and say “Private Cloud and Public Cloud”. As organisations move their internal IT operations into virtualised Environments and begin to see the benefits this will only serve to accelerate the adoption of public cloud vendor offerings from Amazon, RackSpace, Joyent, GoGrid and others.
We already know from a a Forrester survey last year that Enterprises are the surprise adopters of external clouds and we can expect to see increasing adoption of the tier 1 cloud providers (Amazon and Microsoft Azure) as these two companies are the only vendors with the global reach that will allow trans-national organisations (think Pepsi or Cola-Cola) to place their data within the appropriate legal boundaries for their various legal jurisidictions they reside in.
Amazon lowered the bar for European cloud adoption last year with the normalisation of prices between Europe and the US and we an expect to see this trend continue as other vendors make the move into Europe.
