    Rework Your Network When You Move to the Cloud

     

    Have you recently moved to the cloud for some of your business processes? If so, don’t let yourself believe that your network managers have got nothing to worry. You need to rework your network at the time of moving to the cloud. Read on to learn more!
    As an increasingly large number of business organizations have begun to migrate to public clouds, it is not uncommon to find network managers who tend to believe that they’ve got little or nothing to do with the migration.


    Moving certain applications to the cloud network is quick and hassle-free in most cases, but network managers cannot completely isolate themselves from the move. They need to rethink few things at their companies’ network layers.


    Do not Ignore Bandwidth Management :
    Not many SMBs pay attention to the side effects of cloud computing.
    Yes, SMBs moving their apps to the cloud need more bandwidth. Internet connectivity too has to be more reliable.

    So professionals looking after network support functions need to see that the following 3 service level metrics (SLA) are thoroughly reviewed before signing an agreement with the internet service provider:
    1. Bandwidth (With an option to increase it, if the need be)
    2. Availability
    3. Latency

    When applications are no longer hosted inside your building, it’s important that your network support managers take the responsibility of evaluating the internet service.


    More Advanced Encryption :
    Encryption is one of the fundamental requirements for any organization, big or small, that’s moving to a cloud network. Since free IT support from the ISP may not suffice for this requirement, it is advisable to partner with a dedicated managed IT service company that can apply the much needed security controls including but not limited to the following:
    • Intrusion prevention mechanisms
    • URL filtering enabled and monitored
    • Systems for preventing data loss
    • Mechanisms that ensure greater control at the application layer
    Since most small and medium scale businesses can not afford to hire dedicated network security managers, such organizations need to rely on third party IT support companies. It doesn’t even make sense to hire a full time expert.


    Redefine Access Control
    Professionals handling network support functions in an organization moving to the cloud need to rethink access control and authentication policies. That’s important because network managers often ignore IP addresses of computers wherefrom access requests on a LAN. Once the apps are on a cloud network, network managers cannot simply continue to have the same access control and authentication policy.
    Rethinking all of these 3 things at the network layer is an absolute must for any organization hoping to make the best use of the cloud and not find itself in a mess.
