Businesses are gearing up for the next wave of Telcos and the Cloudcomputing Cloud benefits Like many telecom enterprises globally that are compelled to make the cloud integral to their IT strategies, Indias telecom operatorsThe ever increasing need to do more with less continues to drive too are being forced by the market conditions to explore the Cloud.interest and adoption of the Cloud and virtualization. Cloudcomputing in its simplest form can be defined as consumer and The three layers of the Cloud, encompassing - Owing to the global recession and competitive pressures, integrated operators have to construct a path to converge services whilebusiness products, services and solutions delivered and consumed providing quality offerings to retain and grow their customer base.

A rich set of benefits for consumers the need for a shift to this environment. and organizations Migrating to the Cloud: The criticality of the network Traditional communications infrastructure is characterized by stems from the fact that it helps in orchestration of scarce bandwidth, telco-defined services and a focus on Cloud services. The network is undoubtedly a critical hardware. Increasing Capex to support emerging technological These include the following: factor in maintaining the same level of end user needs, business expansion and maintenance costs, poses a experience when clients are moving to the Cloud from Access to massively scalable IT-related major business challenge for organizations. legacy client-server platform. capabilities as a service. Users can therefore Unplanned downtimes, total server failure, high CPU utilization, focus on what the service delivers and not on and natural disasters at data center sites are also plaguing how it is implemented or hosted. Summing up organizations, resulting in huge revenue losses for businesses. Reduction in IT investment and maintenance Vendors are making it easier for network operators toIn such an environment, enterprises - large and small are finding it costs develop new Cloud applications using PaaS, bundled softwareconvenient to access a range of services from the Cloud such as 24x7 availability of applications and stacks, and Cloud operating systems.computational facilities on-demand, storage services, software and infrastructure on a “pay-per-use” Tier 1 Telecom operators will not take up shared Networkvideo applications. Access to a reliable, efficient and robust Operation Center (NOC) services due to network and data privacyHere are a few imperatives for network operators, delivery infrastructure issues.when they outline their cloud deployment plans Flexibility and power of choice, where Currently, these are most popular among Tier 2/3 Telcos for whom The network must be able to scale with an increase in organizations can opt for a private cloud or cost optimization is a major priority. consumption of software, storage and application resources, move applications to the public Cloud. They Shared NOCs are also gaining traction among Telecom Equipment without taking a toll on infrastructure. can also deploy a hybrid model - a blend of Manufacturers (TEMs). on-premise equipment and cloud The network should be simple, standardized (to reduce the Integrated carriers in the Asia-Pacific region offer a separate infrastructure. capital and operation costs if proprietary components are Network Operation Center (NOC) for each service and if using more used), shared and secured to realize cost benefits. than one supplier, an NOC for each vendor network. Network operators must re-architect the data center infrastructure, processes, and applications to harness the Clearly, the converged NOC is the necessary and next logical step in the evolution of the new age converged services infrastructure. Virtualization and power of cloud. Centralization of infrastructure across the ICT industry segments will continue and grow rapidly. Although the Cloud seems to be a little distant now, the fact is that enterprises are already gearing up to meet this next wave of solutions delivery and embrace the future.
