The deployment of off-premises IT infrastructure, or commonly referred to as cloud computing, is a breakthrough for mapping IT infrastructure in recent years. Thought of system uptime (up-time) to decrease in capital costs (capex) becomes a driver of cloud computing adoption. Effectiveness of use in terms of scalability computing power and storage is another advantage that will be felt in long-term use.
But in practice, found many obstacles cloud adoption, especially when associated with the legacy application or even the use of mainframes that until now still in use by many companies. Comparison of the cost and benefits will be felt even smaller if the cloud infrastructure is only in access from within by internal company.
In this case, the on-premise usage for the infrastructure would be a more suitable option to choose from.
The Birth of IT Hybrid
This condition triggers the merging of these two concepts. The design of dualism between cloud computing (or off-premise) and local IT infrastructure infrastructure (on-premise) ultimately gave birth to the term "Hybrid IT" '. Hybrid IT here is different from the term hybrid cloud that combines the use of public and private cloud.
In Hybrid IT, the advantages and disadvantages of each are combined to give birth to a better 'breed'. Potential risks that can occur due to the application of cloud computing is suppressed with on-premise merger. This is especially intended for internal applications used by everyday employees and does not require outside access.
On the other hand, when acquisition and operational costs are higher, plus increased demand for computing-power and storage, it can be answered with cloud computing. For example, web apps that store large images or video files can be helpful with the application of Content-Distributed-Network (CDN), which is already cloud-based. The cloud approach also positively affects the infrastructure that requires high up-time because it is accessed mostly by the client or remote-worker.
AT THE OTHER SIDE, WHEN THE ACQUISITION AND OPERATIONAL COST IS HIGHER, ADDED UPON THE REQUEST FOR COMPUTING-POWER AND STORAGE, CAN BE CLAIMED WITH CLOUD COMPUTING.
The term Hybrid IT is not really a new term in the IT world. This is supported by a survey conducted "The Hybrid Hive" in 2016 over more than 1,000 IT decision makers in seven countries. The survey shows that 40% or at least 400 companies have used Hybrid IT. This is inseparable from a series of digital transformation processes over traditional processes that are continuously being reduced. This is also reinforced by 79% of respondents who say that Hybrid IT is an unavoidable development, especially if the optimization of capex becomes the most important driving-factor.
Why Hyrid IT?
In addition to reducing the potential risks, the use of Hybrid IT can lower the company's operating costs. The decrease in costs is more optimal through a mature strategy and planning. The pay-as-you-go concept can help reduce operational costs.
Amazon Elastic-Compute-Cloud (Amazon EC2), for example, gives customers the flexibility to choose CPU, Memory, Operating System, Networking Capacity, and Access Control capacities. Hewlett Packard with HPE Flexible Capacity solutions provides other competitive values, such as billing refers to the capacity used and not the capacity deployed. In fact all this can be viewed in a single invoice (invoice).
The application of cloud can also suppress the time-to-market of a system to the optimum point. Delay due to delivery during hardware acquisition is no longer a limitation. Snapshot and clone technologies on virtualization in the cloud will make testing easier
