Experts said that SOA is a service-oriented architecture, which can connect different functional units in an application through well-defined interfaces and contracts between these services. The interface is defined in a neutral way, which is independent of the hardware platform, operating system and programming language to realize the service, which also allows the services built in various such systems to interact in a unified and common way.
There is a similarity between SOA and other technologies, that is, there are many misunderstandings about SOA and cloud computing in the industry. Some people even think that the enterprise’s SOA based IT system is to prepare for the shift to cloud computing. In fact, there is a great difference between SOA services and cloud computing services.. [also check saa c03]
In the world of SOA, service refers to software, components, objects and other technical things, but in reality, it often refers to a specific business. Therefore, services in SOA emphasize more on the technical level. In the world of cloud computing, the most concerned is business, not technology; Because you only pay for business, not technology; You need to care about the relationship between business providers and services, not technology and business.
Therefore, CIOs of enterprises should never equate SOA with cloud computing. However, some people think that some confusion between SOA and cloud computing is not necessarily a bad thing. The concept of SOA architecture has great reference significance for cloud computing, and the development of cloud computing technology will also have a positive impact on SOA. (You can see the SOA cases)
In recent years, IT industry is developing rapidly and has become one of the most “fashionable” industries in the world. It is not surprising that similar ideas appear in the field of IT services. What we need to do is to objectively understand these new technologies and ideas.
However, from the current development trend, cloud computing seems to have more advantages than SOA. Most enterprises agree that cloud computing is the general trend of future development. However, cloud computing is still in the primary stage of development. There is no unified standard for different manufacturers, and the publicity of many manufacturers in the market is exaggerated. Although the CIOs of enterprises have expressed that they want to migrate their IT systems to cloud computing solutions, most of them do not know what cloud computing means.
So, what is cloud computing? What are the advantages of traditional IT services that make it distinct?
Many enterprise CIOs regard cloud computing as another form of traditional IT services, but in fact, the value of cloud computing is far more than that. Cloud computing is a new business model and a new computing model, not just providing traditional IT services for users in the form of services through the Internet. It can provide more flexible solutions with lower cost than traditional IT services, and can meet the IT service needs of enterprises of different types and sizes.
However, it is undeniable that cloud computing services also have their shortcomings. At present, cloud computing can not get 100% trust from users in data security and privacy protection. Some experts said that the combination of cloud computing and SOA may give birth to more innovative applications.https://cciedump.spoto.net/aws-certification.php.
