Through virtualization you can enable the Cloud Computing if you are offering 100% virtualization infrastructure with:
- On demand services
- Broad network access
- Resource pooling
- Rapid elasticity
- Pay-per-use model
- Maximize resources:
Virtualization saves a lot of hardware resources and you can get more value from a single server. Maximum time with traditional way of computing most of the servers are under-utilised but with virtualization allows to use the 100% power of them.
- Multiple systems:
Virtualization enables you to create different VMs to run multiple types of applications and multiple operating systems for those applications on the same physical hardware.
- IT budget integration:
With virtualization administration and maintenance of resources is easy for your infrastructure and saves a lot for IT operations.
Whereas, those companies should adopt cloud, which work on operational expenditure model and have less IT staff and very few security concerns should. Cloud basically leverage you with:
- Outsourced IT:
The daily IT administration tasks, care or maintenance, and support system move away from the company to service provider. This will free up your internal IT resources and advances your business quickly.
- Quick Setup:
A startup that adopts cloud from start their work become easy as cloud services is quick and easy. Servers, appliances and application licenses go away when you such kind of service. Even though no need to take care of updates to do the compatibility. Every issue is now on the head of service provider.
All the SaaS (Software as a Service) based application available today with this model of paying of what you actually use. You can customize the services and pay the service provider of what and how much quantity you are using, no extra cost.
By using cloud you have the facility to use it from anywhere and it off loads a whole big amount of IT capacity to the service provider. This increases the scalability of your working environment.
Maximum CIOs says that security and controlling of public cloud is a big concern for them. Security factor is actually different for each company. For example a Government organization who handles individual’s documentation may have different sets of security protocols from Petroleum Company. So the decision of outsourcing the IT services to cloud provider is very crucial for a CIO. Because what works for an organization may not necessarily work the same for another. While considering the public cloud services the potential benefits are important but it is almost important to keep security objectives in mind.
But Public Cloud may provide some of the secure and scalable benefits, such as:
- Department wise:
CIO can easily avail public cloud services as per the department’s need. As public cloud / hybrid cloud services are offered as the way you use them and how much you use them. So easy to get ownership department wise.
Cloud computing is much more different from the traditional way of computing. Cloud as a platform enables a lot of automation and ease in your work. CIOs need to worry about managing the configuration control, security patches, system maintenance & fault management etc.
- Resources Availability:
With ultimate recovery and backups procedures cloud will never let your application down. Due to no geographical restriction, it becomes more robust. So, it’s more reliable where you want 0% downtime.
Public cloud structure is actually designed in a way that you can use it from anywhere and on any device. You can log in from a smartphone and from your office PC too
These benefits also requires more monitoring and controlling for your data. As CIO is unaware from where he is accessing his file or where the image or backup of a VM is lying. There are a few recommended activates which you can perform with your public / hybrid:
- CIOs should refer or check SLAs first before adopting public cloud. Even though Public Cloud SLAs have many term which are non-negotiable, leads to very less visibility and increase more security constraints.
- To enhance the security, control and backup there are few third party tools available. Which CIOs can deploy in their hybrid/public cloud to get everything in single pane solution.
