Outsourcing your IT in a recession economy

Friday, January 2nd, 2009

This past year has been very tough for our economy and as of Dec 1, we are officially in an economic recession (http://www.msnbc.msn.com/id/27999557).  The vast majority of industries in the US have felt the crunch this year.  Many long standing businesses in the US have gone bankrupt such as Circuit City, Linen & Things, Bennigans, Steak & Ale, and others.

 

Traditionally for many companies, the first costs to cut are usually in the IT budget as we all saw and experienced with the 2000 dot com bubble burst.  Many companies learned a valuable lesson from that and we saw a surge of IT outsourcing happen in those days.  Many companies outsourced their software development departments to India and China and the US economy saw a lot of unemployment in the software development industry.  Infrastructure support of course could not be outsourced for any company since you need engineers onsite to build and support your environment.  Back in those days, you only had the option to rely on your inhouse IT support people for this.  As a result, infrastructure support and systems administrators did not feel this kind of unemployment impact.  Unfortunately for businesses, this meant they had to ride out the costs of having inhouse IT support at a premium price.  Over the years, the managed services of infrastructure grew larger and companies like IronTech Solutions answered the call to help support these businesses that were looking to lower costs of IT across the board and not in such niche areas as software development.

 

These days, businesses are more and more dependent on their IT infrastructure than ever before and the impact of the recession on IT outsourcing worldwide has been no slowdown at all.  The outsourced IT industry in Houston and Dallas has seen no slowdown all year.  In fact, IronTech has been signing on new clients for managed services exponentially every month as more and more businesses realize the benefits of having an entire IT department supporting them at a fraction of the cost of hiring one fulltime onsite administrator.  IronTech has also steadily been increasing our staff augmentation services as well with some companies that have a fulltime admin on site, but just need an extra hand with the day to day support of the business both onsite and remotely. 

 

Most small & medium size businesses and their owners are feeling a credit and funding crunch right now.  The solution that most have found is to optimize resources and lower costs wherever possible.  This is where choosing managed services/outsourcing can lead to high profitability for a business because the costs are so low, even with 24/7 support such like IronTech provides.  Companies want to stay flexible and have a highly skilled workforce, while reducing capital expenditures.  Forrester Research says that managed services will see a marked increase for the next few years as more companies realize that benefit of outsourcing their IT according to a study released on Dec. 15, 2008.  Besides the macro economic forecasts, this is increase is lead by two factors:

 

Faster technology change – In the SMB world, think Microsoft Windows Server 2008, Small Business Server 2008, Exchange 2007, Sharepoint Services 3.0, Response Point, Hyper-V, VMware ESXi, etc.  These new technologies offer companies a blizzard of new capabilities without a big hit on their IT budgets.  In fact, these technologies all cut costs in an environment compared to their predecessors.  The companies that choose to invest in these new technologies will see a higher ROI as well since these technologies can lay a foundation in an environment that can upscale for years to come.  Additionally, managed services through IronTech can offer safeguards for all this change.  Do you really want to spend your IT budget in sending your existing IT to training or do you want certified experts in these technologies ready to work for you now?

 

We are on the verge of a technology investment cycle – Even with the economic uncertainty, Information Technology is on the verge of a huge investment cycle.  The IT industry typically operates in a cycle of innovation and growth followed by a cycle of refinement and digestion.  Forrester Research believes that 2009 through 2017 will be a period of innovation and growth unlike any previous cycles.

 

With the savings on capital expenditures, nimbleness of the network, certified skilled workforce, and ability for a business to focus on core business instead of IT, IronTech Solutions expects to see a period unprecedented growth in IT Outsourcing in Houston and Dallas in 2009.  As an award winning managed services provider, IronTech provides desktop support for all users and applications, 24/7/365 server monitoring and support, automated patching and security audits within an environment, server and application hosting in our state of the art Tier 4 data center, and CTO services to provide your company direction in infrastructure as your core business grows.  Our pay as you go business model allows small and medium size businesses to easily scale up or scale down based on the number of users at the company and what business needs have to be met.  All this is provided at a low monthly flat fee so there are no unexpected costs and a business has total control of their IT budget.

Server Virtualization for SMBs explained

Saturday, December 13th, 2008

Server Virtualization refers to a complete operating system that runs in a guest virtual machine (VM) on the host operating system.  This host operating system is know as a “hypervisor” (such as VMware ESX, Microsoft Hyper-V Server 2008, and Citrix XenServer).  This guest VM is completely independent of the host operating system and can be moved from one server to another or even run on another hypervisor platform entirely if converted.  Since each guest VM is completely enscapsulated, you have the ability of running multiple VMs on one server.  The hypervisor which sits between the physical hardware and the guest VMs manages the shared resource allocation of the server.  This allows you to take advantage of the resources of a physical server that would otherwise sit idle.  When you tally up the cost of electricity, air conditioning, space, battery backups, etc., you will find that if your environment has many servers, the costs can get very high very quickly.  This is where server virtualization has it’s greatest benefit.  Add to this the flexibility of moving your server to another server on the fly in the event of a hardware failure of disaster scenario, virtualization goes from being a “cool trend” to a “must have” for many companies these days.

ESX, Hyper-V Server 2008, and XenServer Enterprise are all “bare-metal hypervisors” which means they do not require an operating system installed on the server at the time of the hypervisor installation.  They are in essence their own OS.  You will notice however that ESX is based on Linux Redhat and Hyper-V is based on Server 2008 Core.

 

The other kind of hypervisor is the software hypervisor that requires a host OS already installed on the server or desktop to run.  Examples would be VMware Server, XenServer Standard, Hyper-V (the one that ships with Server 2008, not the baremetal version above that you have to download online).  The good thing about using a software hypervisor is that you don’t have to reformat an existing server to install a hypervisor.  You can continue using the existing server as you always have with the added benefit of having one or more virtual servers running right along side it.  The downside of using a software hypervisor package within a host OS is increased overhead. 

 

This is just the tip of the iceberg.  There are so many virtualization options available, which one is correct for small and medium size business?  Most SMBs typically enter the virtualization market for two reasons:

 

1. High availability of a server (such as a mail server, web server, etc.)
2. Total cost of ownership & ROI (the company realizes that buying yet another physical server is not cost effective)

 

The next question an SMB should ask is how much is it going to cost to virtualize and consolidate your servers?  Without going into too many details and comparisons of features, the typical small to mid size business can virtualize for free using a free hypervisor as long as your exisitng physical server will support it:

 

1. VMware Server – FREE
2. Hyper-V Server 2008 – FREE

 

While other hypervisor options include many different features, using VMware Server or Hyper-V Server 2008 are two ways an SMB can see what a hypervisor can do for them without the making a huge investment in buying Enterprise class software such as VMware ESX or XenServer Enterprise.

 

VMware Server should be considered the entry level hypervisor for SMBs.  This is absolutely free and will install on your existing Windows 2003 Server just like any other application.  The hardware requirements are flexible.  The only thing you have to worry about is having enough RAM available for your guest machines.  VMware Server cannot be used for high availability, you will have to purchase it’s bare-metal big brother ESX.  Using VMware Server is a great way to see how powerful virtualization can be in your environment first hand.  If you choose not to go the virtualization route for whatever reason, just uninstall it from your server just like any other application.

 

Hyper-V Server 2008 is a free download on Microsoft’s website.  One important point to note for Hyper-V is that since it is a bare-metal hypervisor, you cannot install it on an existing server without first formatting it.  The hardware requirements of Hyper-V also have to be met.  The biggest problem SMBs usually face is that their existing server is not 64 bit and the processor does not support hardware assisted virtualization (Intel VT or ADM-V).  Most SMBs will likely have to purchase a new server for this purpose since these hardware specs have only been in the market for just over a year now.  So for an SMB that wants to get a taste of actual bare metal virtualization at the cost of purchasing a new server, Hyper-V is an excellent choice.  The good news is that this is completely scalable.  If you want to purchase additional servers and setup multiple Hyper-V servers, you can basically “daisy chain” them all together and create a high availability solution.  If one physical server were to fail (let’s say a power supply goes out), it will Quick Migrate the servers to other physical servers as long as you have some kind of shared storage setup between all the servers.  Your users will never know something has happened since the migration is seamless.

 

In summary, there are many configurations and flavors of virtualization available these days.  The solution you need will depend on what requirements your business has and what the budget is.  IronTech consulants are certified virtualization specialists that can help you choose what’s best for your company on a variety of offerings from Microsoft, VMware, and Citrix.  We have virtualization demonstrations available in Houston and Dallas and can even give you a “loaner” server to virtualize some of your servers to show you how seamless yet powerful server virtualization can be.
