How Virtualization can help customers meet their business needs faster and save costs and reduce carbon footprint

Other than cloud computing, I keep hearing about Zumba dancing and virtualisation/virtualization. I’ll stick to the American spelling in this blog post.

What do they all have in common? Latest buzz words!

Although Zumba dancing (dance aerobic) has a link with energy, my point is they’re all the latest craze, trends, what’s being talked about, what people are following….if you know what I mean.

Anyway in Green IT, cloud computing and virtualization are being described as the future of IT. They offer many financial and environmental benefits, and once again, have proven to do so.

As mentioned in a previous blog post, virtualization isn’t really anything new. It’s something which was being used at a company I worked at quite a few years ago. They always kept up to date (and still do) with the latest technologies.

With virtualization, you have desktop virtualization, server virtualization, network virtualization and more.

To describe it simply, you’re basically connecting to another machine. You may use Microsoft Terminal Services, Virtual Private Network (VPN), to access/use the software, applications, data, run database scripts, etc., which are basically not stored on your own PC. You would log on locally onto your own PC to use the software which has been installed on it.

As your business grows the need for services increases. As the needs for services increases, new IT application systems may be required, more storage space, more operating systems, etc.

The IT department must always implement cost-effective solutions to ensure the needs of the business/customer are continuously being met. The business may also grow because companies have merged.

I recently received a letter to inform me that I wouldn’t be able to access a website for a day due to the merge of two companies. My assumption is they have migrated all their data, new websites and systems to one central location (perhaps). They will therefore have to ensure the migration to the production/live system has worked ok and has been thoroughly tested again, before their customers can access it. That’s one day of down time (unavailability).

• Do you know where the IT  application systems you use are kept?

• Do you know where your e-mails are being kept?

• Do you know where your databases are and how many you have?

• Do you know how much storage is being used?

• As a tester or user of an application system, do you know if you have separate servers set up (in the ideal world!) for unit testing, system testing and the live/production environments for each of these?

• Do you know how you’re connecting on to the intranet or internet?

• How many Data Centers (staying consistent with the American spelling) do you have?

Is your data stored on or off site? It may be outsourced.

• Do you have any servers under your desk or located in different offices?

• Do you have blade or rack servers?

• How much space is being occupied with the servers?

• Are servers being left on 24/7?

• Do you have Oracle servers, SQL servers, etc?

• How many operating systems/versions do you have?

• Are you using open-source software?

• How much is being spent on buying new hardware servers and how often?

• How much time is being spent by IT staff maintaining the servers?

• What impact does it have on the business when servers have to be taken down when an update or fix is required?

• How long are servers down for (downtime)?

• What business critical systems are held on which servers?

Are there any systems no longer being used by the customers/employees/staff/users?

• Are your servers being accessed globally?

• Do you have documentation on who has access to applications/data/servers?

• Do you have physical and/or virtual servers?

• How much heating/cooling/power is being consumed?

• How much are you spending on hardware, licenses, software etc.

• How long does it take to deploy new servers?

• Are all your servers from the same supplier/vendor?

• What support do your suppliers provide and also, not support?

• How do you back up your information/data?

Again, endless questions….

There are over 20 benefits of virtualization, such as  quicker systems delivery time, reduced carbon footprint, reduced processing time and time saved.

There are many companies who have had their costs saved and carbon footprint reduced through virtualization.
