More than ever, companies are readily accepting their future as users of cloud based services. According to the State of the Enterprise Cloud Report from Verizon, enterprise use of cloud computing solutions grew 90 percent between January of 2012 and June 2013, and corporations have moved beyond testing and development by running external facing and business critical apps in the cloud. With more applications readily available, used by 60 percent of companies, the cloud has become widely accepted within the business community.

"Enterprise cloud has reached a tipping point," the report said. "Organizations have seen the benefits cloud can provide - both in efficiency and cost - and are ready to move an increasing number of mission-critical applications to cloud-based infrastructure. However in order for this to happen, cloud service providers must deliver to enterprise-grade availability and security."

Other  than applications, companies are investing in ways that they can become more efficient, improve memory and storage capacity and be more productive. With this in mind, deployment of virtual machines increased by only 35 percent in the same period. However, companies are spending 45 percent more per month on cloud based services, showing that it is not all in an effort to simply reduce costs.

Enterprises are now looking for the best possible uptime and availability when it comes to choosing a service provider, as these apps are now business-critical and it is essential to minimize downtime.

Factors to be aware of with adoption
Cloud professional Mark Geene told TechTarget in an interview that there are some key challenges that enterprises face when adopting cloud computing solutions. For one, he said applications rely on many different services and need to be managed correctly.

"When is a service going to be down? What are the notifications? Are there response time issues?" he said of questions organizations should ask." Then you have to track and monitor the notifications and response time, error rates, etc., for those services you can manage. You have to maintain where the API (application program interface) changes and make up dates to the code and the API potentially over time, and you have to do that for more and more services.

Geene said it is essential to create a layer between the application and service to have things run smoothly. He spoke about one company that had a payment service hard coded to an API. This meant the application had to be rewritten, which cost an additional 60 hours. Enterprises must be aware of these issues when adopting the cloud.
