“Cloud computing is not only the future of computing but the present and the entire past of computing.” – Larry Ellison
Numerous businesses have already been aware of the advantage of what cloud computing could bring to an organisation. Not only does it give integrated access to almost anything in many applications, but the cloud can also enhance our work mobility and flexibility that can help the whole organisation team to simplify things, plan effectively, and avoid a huge stack of paperwork. Additionally, the cloud has also eased human resources workload in terms of accessible scalability and flexibility, resulting in an effective data-driven HR.
According to statistics by TechJury, the cloud will surpass the $100 billion mark and reach $150 billion by the end of 2020 with more than half of enterprises will shift to cloud-based data in their infrastructure. Thusly, it is no surprise that cloud computing will dominate our world of work in the future – even, it is already starting now.
But, is there any downfall in cloud computing?
Albeit the positive impact of cloud is almost instantaneous, cloud, just like any other technologies, also brings several risks that could endanger business sustainability. One of the biggest fears of cloud failure is its security system. David Linthicum, a senior vice president of Cloud Technology Partners and an expert in the cloud industry, said that the cloud is polarising – it is either you will spend too much money on security or, conversely, not enough data security.
Lloyd’s report published in Reuters also revealed that the risk of cybercriminals is higher in cloud-based data. There was approximately $19 billion of business losses due to cloud security failure last year. In addition, businesses that already adopt this technology should be more aware of cyber incidents, especially hacking, lightning strikes, bombing of data centres and human errors.
Other than IoT attack, the cloud might also be threatful in terms of updates, service attacks, and crashing due to poor design. For example, Salesforce went offline due to updating system that lasted for more than 24 hours, resulting in extensive business damage with customers losing hours and hours of data. After the downtime, however, Salesforce moved to Amazon Web Services for most of its workloads. Not only Salesforce, but Netflix and Microsoft Azure also underwent the same failure resulting in rebooting production for Netflix and massive outage for Microsoft. Other issues such as authentication problem, data verification, tampering, loss, and theft, data secretion, or recovery problem are also prone to happen when moving to a cloud system.
So, how to minimise the risk of cloud failure?
For security purposes, you need to find a balance for cloud security, advised Linthicum. You can begin with your requirements and then work up to the technology. You should also properly plan and deploy cloud environments that all effective security has. For instance, begin with a unique system like no more using “password” as a password. Code should also be encrypted in transit to raise the barrier to the cloud hackers trying insertion.
Another way, you should choose cloud partner you trust. Although failure is unavoidable even in a robust cloud system, by choosing wisely, you can at least lessen the chance of data leakage or data crash. Duplicating your information and data would also be helpful, especially when updating cloud system fails.
