Fifth Era — Cloud computing The first era mainframe and minicomputer computing was ruled by IBM and their mainframe computers for which they supplied both the hardware and software. These computers would often take up whole rooms and require teams to run them. As technology advanced, these computers were able to handle greater capacities and therefore reduce their cost. The second era personal computers began in as microprocessors started to compete with mainframes and minicomputers and accelerated the process of decentralizing computing power from large data centers to smaller offices.
Which resources you choose for your delivery, cloud-based or local, is up to you. Cloud computing has benefited many enterprises by reducing costs and enabling a focus on core business competence, rather than IT and infrastructure issues.
Despite the general hype, there can be disadvantages to cloud computing, especially in smaller operations. In this post, we will explore some of the key disadvantages and share tips and best practices that your teams can employ to address them.
Disadvantages of Cloud Computing Explained 1 Downtime Downtime is often cited as one of the biggest disadvantages of cloud computing. Since cloud computing systems are internet-based, service outages are always an unfortunate possibility and can occur for any reason.
Can your business afford the impacts of an outage or slowdown?
Best Practices for minimizing planned downtime in a cloud environment: Design services with high availability and disaster recovery in mind. Leverage the multi- availability zones provided by cloud vendors in your infrastructure. If your services have a low tolerance for failure, consider multi-region deployments with automated failover to ensure the best business continuity possible.
Define and implement a disaster recovery plan in line with your business objectives that provide the lowest possible recovery time RTO and recovery point objectives RPO.
These services provide a dedicated network connection between you and the cloud service point of presence.
This can reduce exposure to the risk of business interruption from the public internet. We must not forget what happened at Code Space and the hacking of their AWS EC2 console, which led to data deletion and the eventual shutdown of the company.
Their dependence on remote cloud-based infrastructure meant taking on the risks of outsourcing everything. Of course, any cloud service provider is expected to manage and safeguard the underlying hardware infrastructure of a deployment.
Though recent breaches of credit card data and user login credentials are still fresh in the minds of the public, steps have been taken to ensure the safety of data. Nonetheless, you still need to be aware of your responsibilities and follow best practices.
Best practices for minimizing security and privacy risks: Understand the shared responsibility model of your cloud provider. Implement security at every level of your deployment. Know who is supposed to have access to each resource and service and limit access to least privilege.
Solid security skills for your cloud teams are one of the best ways to mitigate security and privacy concerns in the cloud. Take a risk-based approach to securing assets used in the cloud Extend security to the device.
Implement multi-factor authentication for all accounts accessing sensitive data or systems. Even the best teams suffer severe attacks and security breaches from time to time. After all, no one at a cloud vendor checks your administration skills before granting you an account: Best practices to help you reduce cloud attacks: Make security a core aspect of all IT operations.Seth Noble is founder and president of Data Expedition..
