9 Tips for Test-Driving

A Cloud Computing Service

Many Cloud Service Providers (CSPs) offer free trials before signing up for their services to reassure their clients of their reliability.

Here are nine important things you must check when taking a free cloud trial.

Getting Started with Cloud

Identify Your RequirementsMeasure carefully the performance, security, and other expectations you have from your cloud service.

Understand the Services that the Vendor ProvidesUnderstand the financial cost, opportunity cost, service deployment, tools required, moving cost and employee training.

Understand the Geography of the ServersNetwork Latency is different in different countries and also different for different servers, companies, and providers. 

Understand CSP LimitationsAlthough the cloud is said to be highly scalable and elastic, it has limits which include number of service requests, bandwidth, and the number of servers.

Test Before You UseA bunch of parameters have to be tested before you think of purchasing a cloud solution which are explained in the following slides.

Elasticity Although in theory it is

easy to trust the elasticity of the cloud, there could be several issues in practice. For example, over scaling may affect the speed of deployment.

PerformanceTest the service for number of users that can work together on the system, the distribution of data storage, the speed of access and the number of requests.

VulnerabilityTesting the vulnerability of the cloud to identify weak encryption, open ports, and other weaknesses is an important part of the testing process.

ReliabilityWhen testing your applications, check what happens when certain components are not available and how your application performs at peak times.

Choose your Plan with CareCheck the options that different vendors have to offer and select the one that best meets your requirements.

Pricing and Discounts Check the costs of

services offered against the ROI to your business. 

Often monthly payment packages are available at discounted rates.

Free parallel run before purchase helps to compare time frames, performance, productivity and other parameters to decide the cost efficiency and feasibility of the move to the cloud.

Parallel Run

Fall Back Even when you take the final

step, it would be wise to have a fall back procedure in place.

It will ensure sustainability in the event your cloud service collapses or fails to meet your requirements.
