What does the term “cloud” mean? This terminology has become a marketing buzzword, being constantly used by salespeople to attract attention, but the true meaning behind the word is rarely understood.
The term “cloud” is used to describe the supply of technology as a service, rather than a product. Since “cloud” can be such a broad term, we will examine how it relates to one entity: Enterprise Applications. Today, many of these types of applications are available, such as Workday, NetSuite, QuickBooks, and Oracle On Demand. Instead of manufacturing or maintaining in-house IT infrastructures, companies can buy what software they need as a service. Now, companies do not need to invest millions of dollars in hardware or IT resources, but rather they can just pay operational expenses. Small to mid-size companies especially see the value in this; they get all the advantages of a large corporation without the exorbitant cost.
The SaaS approach, however, is not without its challenges. Although this solution will satisfy your present needs, it does not offer as many options as in-house hardware. The EAaaS approach (Enterprise Application as a Service) provides a greater level of customization. This service is bundled with all kinds of network, storage, systems, DBA, and administration support. EAaaS brings in a new world of opportunity, which allows both customers and database administrators to transition from legacy to cloud.
