Cloud computing is all in one solution with many advance and sophisticated technologies bind together. Basically cloud computing means using the resources and data over the Internet that are kept or hosted somewhere else in the world. This is very beneficial to small as well as large companies. Usually web browsers and command line interfaces are used to retrieve the cloud services. Buying cloud services is not an easy task.
There are a number of factors to consider when choosing a cloud computing vendor. The good news is that many cloud service providers do not have long-term agreements and would not lock you in place for a long time. In many cases, it is reasonable to carefully evaluate the provider before signing the agreement, since the process of moving from one vendor to another is likely to be cumbersome.
Things to consider before Buying Cloud Computing
Here are some of the technology sided things you need to ensure that your cloud computing vendor is providing:
#1 Support tickets should be Quickly troubleshooted
When you buy cloud computing, basically you must ensure that your operating system and other processors are supported. Apart from that you must also ensure that the vendor provides the quick troubleshooting to the common simple problems related to cloud computing. If a simple task requires you to open a troublesome ticket, so calculate the waiting time for the risk of supporting your Employees response.

Cloud computing Downtime refers to the situation when a cloud service is not accessible to users via the internet for a certain period of time. So this situation should never occur and should be avoided. But there are cases when the well known best cloud providers experience the downtime, so in order to be at safe side please check the downtime history of the providers before you buy Cloud Computing services.
#3 Disaster Recovery Process
If you are doing a
disaster recovery process, your existing virtual server may be sent to the cloud provider
as it is for use. Typically a vendor must maintain a special operating system with a specific IP address used to back up and monitor the data, these would connect to the actual address of your operating system. So ask the Cloud Computing vendor about the Disaster recovery, backup and monitoring process.
#4 Security of cloud computing
Who want that their Company's confidential data should be placed in a server without any security. Cloud vendors should provide very standard level security measures and protocols which should be updated regularly in order to avoid theft and loss of the data from cloud. You must also see where are the physical data center of the Cloud computing services and know about the security of their data center.
Different security services like
Antivirus for virus and malware detection,
Firewall to avoid unauthorized access and
Data Encryption and many more such security services should be provided by the Cloud Computing vendors.
#5 Pricing Model for Cloud Computing services
When you buy cloud computing services, you must look for the vendor that has easy to understand pricing model and whom monthly cost can be easily predicted. Many cloud computing vendor would provide an internal billing facility to your company's different departments where the costs can be calculated on every day basis or even hourly prices are mapped. If you are managing the operating system and considering integrating the application, which may not be ready for use then it will incur additional costs.

If you need to build images from scratch and carry out data migration or you need a database to run then check out their ability and speed to connect to a traditional dedicated server. If you want to run any type of clustered database then you must clear this before buying cloud computing services because many cloud services providers can not provide a database cluster.
Some cloud providers are tweaking toward "full-time" applications so that applications can always run in their own environment. These servers are often paid daily and can be turned on and off at will. Automatic contraction and expansion of computing resources may not be part of the service.
You must carefully determine what you need:Like whether you want cloud to send overload or you want cloud to put your application entirely beyond your own data center.
#7 Signing Long terms Agreements with Cloud Computing vendor
You must avoid signing long-term agreements with cloud service provides unless there is a lot of room for cost savings which allows you to master your own needs. Since the cloud service uses pooled resources, the provider can not explicitly have the specific deployment of your investment unless you have specifically dedicated resources assigned to you.

Also check whether or not the cloud computing provider is providing any legal agreements, in case you data is lost or deleted or theft. Service Level Agreement (SLA) would help you compensate the data loss. So check for this provision before buying cloud computing services.
#9 Timing to Consider
Another investigating factor for cloud computing is timing. As you can never know when an item requires an extra server and whether you need to test an application late at night. So check out the whether or not their systems are automatically allocating the different services and if not how much time they would take to help you in any part of the day or night if needed.
So these were some of the main points that you must remember before buying cloud computing. At last you must also ask the cloud providers
How you should be able to access your Company's details in the cloud? You must be provided with the login address and passwords to access and manage your cloud services from anywhere at any time using Internet.
