The Virtualization Practice

Cloud Computing

Cloud Computing focuses upon how to construct, secure, manage, monitor and use public IaaS, PaaS, and SaaS clouds. Major areas of focus include barriers to cloud adoption, progress on the part of cloud vendors in removing those barriers, where the line of responsibility is drawn between the cloud vendor and the customer for each of IaaS, PaaS and SaaS clouds, ...
as well as the management tools that are essential to deploy in the cloud, ensure security in the cloud and ensure the performance of applications running in the cloud. Covered vendors include Amazon, VMware, AFORE, CloudSidekick, CloudPhysics, ElasticBox, Hotlink, New Relic, Prelert, Puppet Labs and Virtustream.

A customer recently asked me, can we virtualize our Tier 1 App that receives 7Billion requests per day? My initial response was, on how many servers? Their answer was 15. This is quite a shocking set of numbers to consider. Add into this numbers such as 150K sessions per second, the need for a firewall, and sub-second response time and you end up with a few more shocking numbers. So could such workloads be virtualized? or is it too big for Virtualization?

We, here at The Virtualization Practice, are getting ready to have a cloud presence. Since we ‘eat our own dogfood’ with a 100% Virtual Environment, we are gearing up to move some of those workloads into a hybrid cloud. We already use some cloud resources, but now is the time to look at other workloads. Why we are moving to the cloud is three fold: how can we write about various aspects of being a tenant in the cloud, if we are not one; a recent power outage at the grid level; and a upcoming data center move. Two of these reasons are all about business continuity with the first being what we do. While we already have a cloud running within our own environment, it is time to branch out.

The OpenStack conference 2012 is full of OpenStack fans, aficionados, developers, and companies making a business using the ecosystem. However, I kept hearing that openstack was a replacement for VMware. So why is this even a possibility, and why did Rackspace and now HP build public clouds using this technology? The easy answer is to save money. But is that the only answer? What is OpenStack and why is it becoming important?

EMC VSPEX is a converged infrastructure offering targeting private clouds offered through EMC and VMware VAR’s. This focus upon the channel makes this the first “private cloud in a box” that is explicitly designed for VAR’s and SI’s to take to their mid-market customers. As such the potential for such an offering is huge. However it is highly likely that the success of VSPEX will be clouded by EMC’s less than stellar track record with the channel, and the complete absence of management software from the offering.

Citrix acquire Podio – Podio’s focus is to provide a platform for small/medium sized organisations to get up and running with standard business function applications offered from Podio’s own App Store. Does this mark the a Citrix foray to better accomodate mobility and consumerisation while stepping outside the microsoft windows desktop delivery environment.

While at InfoSec World 2012’s summit on Cloud and Virtualization Security, the first talk was on Securing your data. The second was on penetration testing to ensure that data was secure. In essence it has always been about the data but there is a huge difference between what a tenant can do and what the cloud or virtual environment provider can do with respect to data protection and security. This gap is apparently becoming wider instead of smaller as we try to understand tenant vs cloud provider security scopes. There is a lack of transparency with respect to security, but at the same time there are movements to gain that transparency. But secret sauces, scopes, legislation, and lack of knowledge seem to be getting in the way.

There is a difference between outsourcing layers of your infrastructure and making the organization to whom you have outsourced those layers responsible for them, and losing all rights to change those layers in support of your business and application needs. Careful contract and product decisions need to be made in order to ensure that when you used a managed cloud service, you are not giving up the control you need to be agile and responsive to you business constituents.
