There are a number of drivers for moving to the cloud. The public cloud offers a number of benefits over on-premise virtualisation, including cost savings, faster deployments and better performance, scalability, flexibility, and the ability to shift budgets from capital expenditures to substantially reduced operational expenditures. The second most important driver for cloud migration is data modernisation, that primarily involves moving data from legacy to modern databases. Moving to the cloud can enable operational agility and greater efficiency. But, despite all the benefits, not all enterprises are migrating to the cloud – even today, a lot of them operate traditionally via data centres. Even though cloud computing presents many exciting business benefits to enterprises, concerns about the security of public clouds still persist. Because of the “public” and third-party nature of the cloud, many enterprises are hesitant to make a full switch from on-premises, private IT to cloud IT. But ISPs and telecom providers can reduce this unease by providing in-country public clouds that are more secure and compliant.
The public cloud has myriad benefits
In the world of enterprises and governments, the benefits of cloud computing are well known. Through IaaS/PaaS/SaaS offerings, public cloud infrastructure can help both large and small enterprises. Here are the major benefits of cloud computing for organisations:
- Hiring cloud infrastructure rather than the outright purchase of hardware and software helps businesses reduce their capital and operating expenditures.
- A public cloud enables location-agnostic computing, which encourages collaboration between internal teams and external partners. The result is more innovation and richer data analytics.
- Network administrators can outsource complex disaster recovery plans to cloud vendors by renting storage space from them.
- Cloud service providers offer best-in-class technology to enterprises of all sizes. Small and Medium Enterprises (SMEs) can get enterprise-class technology via the cloud.
- Cloud vendors can help reduce enterprises’ operating expenses on the maintenance of servers and applications.
- Public cloud vendors can help enterprises manage their documents better by providing a single storage location and the applications to manipulate them.
- Enterprises get the flexibility to scale up or down their use of bandwidth and storage based on their needs.
- Cloud service providers protect their cloud infrastructure physically and digitally by using the best encryption, anti-malware, and antivirus tools. They take these costs off the hands of their customers.
But security-related worries persist
Despite the success of cloud computing as a concept and a business, many enterprise IT teams doubt the robustness of the security of cloud servers and infrastructure. There are a number of reasons for this. To begin with, in order to alleviate the problem of underutilisation of the infrastructure and optimum usage of computing power and storage capacity, cloud service providers offer virtualized environments in a multi-tenant configuration. When a number of subscribers are running their programs and storing their data in a multi-tenant environment, there is always a tinge of worry regarding data spoofing while it’s sent from the clients to servers or data leakage etc. Further, there’s always an apprehension about the uncertain location of the infrastructure, especially the data storage and the absence of awareness of rules that are globally and locally (especially locally) accepted about data security and privacy. Unauthorized access, shared infrastructure and multi-tenant environment – all pose a number of vulnerabilities.
Their primary fears are that
- faulty cloud APIs can leave their data vulnerable,
- storage misconfiguration could lead to a security breach,
- tracking users, permissions, and access could be difficult,
- network latency could slow their transactions,
- compliance with local laws could be an issue,
- forex outflow could raise costs,
- their control over their data could reduce.
These worries are delaying the migration of their storage, processing, and application needs to a public cloud infrastructure. But there are powerful arguments in response to these worries.
The most important reason enterprises would choose the cloud is the same reason that discourages them from doing so: someone else is handling the work instead of you. But the strongest argument favouring the cloud is that while most businesses may have only a couple of people focusing on security, a cloud vendor would have entire teams securing the data and the infrastructure. The key question is: Can your organisation secure your data better than a dedicated cloud provider?
