The Digital start ups born into the a cloud era can quickly disrupt traditional business models and the grow unencumbered by legacy IT platforms. It’s a different story for many established the enterprises. The Legacy applications and the systems are an important component in nearly all established organizations. With in the investments already made, it’s hard to abandon them when new technologies like cloud become the available. Cloud computing has enabled a convenient and on-demand access to a shared pool of computing resources like networks, servers, storage, applications etc. Then cloud migration is the process of partially or completely deploying an organization’s digital assets, services, IT resources or applications to the cloud. With in the cloud computing technology Enterprises and SMBs can get unlimited resources at their disposal based on their dynamic requirements and also giving our applications a wider accessibility. Conceptually software applications can be split into two general parts - state and behaviour. The state of the application is the data and it means. The behaviour of an application is the functionality and how it behaves. This is ingrained into most software developers and we can learn this very early through techniques like object-oriented programming.
There are the several benefits associated with a cloud computing. We can lower our costs, based on our changing need of hardware and software, and the gain utility based pricing for the a services our access or need at a certain time only. Then Corporations worldwide are adopting cloud computing as the main computing platform for conducting their day-to-day business. They have abandoned or severely cut back on capital expenditures and maintenance for on-site servers, storage devices, business applications and backup devices such as tape and optical drives. A collaborative environment is the created which improves accessibility to hardware resources, and reduces the overhead cost. The cloud computing poses a lot of challenges, especially when considering migrating to the cloud. Here there are a few things our need to consider when moving your system to cloud based services.
Equipment failures and the outages are common for a system. We need to consider cloud computing solutions that take this into account, and use of redundant network switches, servers and storage facilities, which make the systems available even during failures and outages. When our are looking for cloud computing vendors, our should consider fully redundant IP connections, which offer secure access even during equipment failure or local disaster. MPLs improve reliability by adding additional security layers. When moving to the cloud, the management of the infrastructure is a crucial point, one that you should consider.
When we are moving your legacy system to cloud, security is an important consideration. You should choose vendors whoes offer secure and reliable cloud computing solutions. We will see that vendors have taken security pretty seriously. With their experience and quality tools, they have ensured that accessing the data is secure. Why are IT managers reluctant to make the move to the cloud? Moving to the cloud means committing to the new cloud infrastructure. A lot of cloud computing providers are offering fully managed cloud environment. Firewall and password protection is considered majorly for SaaS and IaaS services offered by these vendors. Many enterprises consider private network to double the security layer being offered. The VPN or IPSec connections offer secure data capture as well as interception from the cloud to the worker desktop. In some cases, the multiprotocol label switching network is considered to route the traffic and maintain security. For more
