Cloud computing has aligned with market needs today. The demand is pretty high and hence the demand for service vendors is on all-time high. As various business clients are fighting with issues of extreme cost, complexity in logic and need for increasing speed, cloud technologies are looked upon as a vehicle for change. Today, implementing new applications requires a specific budget especially for processes required including designing, building and testing. Also, there are no upfront infrastructure costs which help small and medium companies to settle and do business.Application development is dependent on hardware, storage along with strong network availability. Project schedules face lagging due to different dependencies.
The cloud is one of the primary platforms for many organizations and aids application development of varying periods. It has recently become the biggest focus in the IT community. For decades, there was no solution for companies who required more data and computation capacity, since they had to invest in hardware or increase the efficiency of IT operations.
This put an additional burden on the finances. Nowadays, cloud computing has offered an affordable approach to IT delivery with the leasing option of processing capacity from different interconnected, shared computing systems which are maintained by several cloud service providers. Cloud computing benefits are many including agility; elasticity and cost-efficiency. One can scale resource allocation schemes as and when wanted from different cloud services providers.
It is necessary though that the software of the cloud services need to be engineered specifically. Many organizations find it better to migrate their existing applications to well-known, efficient cloud platforms. Migration sorts out differences between different programming models along with data storage and differences in processes including quality assurance, different development methods and platforms, software implementation approaches, security, and varied deployment options. Each of them need to be addressed while implementing practical cloud-based services and solutions, especially if the solutions are required for an industrial setup.
A new cloud platform architecture has taken birth recently called Data Protection as a Service which aims to reduce the per-application development effort which is required essentially for data protection while allowing maintenance operations. To analyze the cloud dependability, one can assess the services provided by Amazon Web Services. The performance variability of cloud services is assessed and researched for effectiveness for large-scale applications.
There is a huge challenge to enterprise adoption since cloud technologies do not grant visibility into the effort and cost of migration. One can alternatively opt for an approach to generate test methods for simulating the behaviour of real-time environment. One can test cloud applications hosted on the cloud and then offer support for cloud development processes, automated software engineering techniques for the cloud.
There are tools which support decision-making especially during the migration process of IT systems to the cloud. The modelling tool establishes the cost of IaaS. It helps in comparing the cost of a plethora of cloud providers and varied deployment options. The second tool delineates the benefits and risks of making use of IaaS from the enterprise perspective and provides the early peep into risk assessment. The cloud services providers assist many organizations in more ways than one and deliver what they do best, by offering cost-effective scalable resources for everyone.
