Today, Cloud computing being one such recent technology innovation has grabbed the attention of global business managers, Cloud services have gained significant prominence in the recent years. Global companies specifically IT sector has been extensively using cloud computing in the recent years. Widely varied business domains which includes retail, healthcare, banking, finance, facilities, and government organizations are extensively using cloud services in the recent years.
Cloud computing delivers significant business benefits and enables global firms to simplify their business critical processes and gain efficiency. Firms that adopted cloud seemed more efficient in handling their business operations.
Global business managers mainly focus on optimizing the resource utilization and lower the capital and operational costs to achieve significant business growth.
Despite of rapidly growing cloud adoptions across the globe, firms operating under strict regulatory authorities are still reluctant to store their sensitive data on cloud due to security concerns, Ravi Namboori adds.
Data security being a major concern significantly influences the overall IT decision making process causing dilemma for business managers whether to opt for cloud storage or stick to their existing traditional in-house data storage practices, says Ravi Namboori a Cisco evangelist.
When an organization is planning to move their data and operations on to cloud, business owners will keenly look in to important aspects such as design, cost, connectivity and security.
Today, security in IT environment is not only about authentication and authorization but it is a multidimensional aspect particularly in cloud storage practices.
Further emphasizing on multiple layers of cloud management software, it is necessary to safe guard data and network system on the whole. Server instance operating system being a key layer usually comprised of two firewalls setup in a fault tolerant or high availability (FT/HA). It is positioned at the edge of the data center to protect the set up on the whole.
When it comes to protecting cloud environment, firewalls are placed at the edge of the cloud and TCP/UDP ports are restricted travelling in to and out of the cloud setup.
Infrastructure and computing nodes are protected by firewalls and expose API interface, or just protect virtual machines which communicate within and outside of the cloud environment.
Protection inside the cloud can be achieved by using LDAP authentication methods and mechanisms for all user authorization and authentication purposes. Other security tools such as virtual firewalls and virtual edge routers will be used by cloud management tools to ensure overall cloud environment is secured.
