Amazon | Computing Cloud 2021


You’ll need to estimate all types of resources, including CPU, memory, storage, and network connectivity if you wish to supply digital services of any kind. It’s entirely up to you whether you use cloud-based or local resources for your distribution. However, you’ll want to finish your homework first. You’ll need to know the benefits and drawbacks of cloud computing, as well as how to contextualize any existing drawbacks.

Many businesses have profited from cloud computing since it lowers expenses and allows them to focus on their core competencies rather than IT and infrastructure difficulties. Despite the overall buzz about cloud computing in the IT world, there are certain drawbacks to it, particularly in smaller businesses. Let’s look at the benefits and drawbacks of cloud computing, as well as how to interpret and contextualize any existent drawbacks.

We’ll go over some of the major drawbacks in this article, as well as some recommendations and best practices that your team may use to overcome them. Use a systematic, process-based approach to understanding cloud security, such as Cloud Academy’s Security – Specialty Certification Preparation for AWS Learning Path, to speed up the process.

Disadvantages of cloud computing explained.

1). Downtime

One of the most common criticisms of cloud computing is that it causes downtime. Because cloud computing systems are internet-based, service interruptions are always a risk and can happen for a variety of reasons.

Can your company afford the consequences of downtime or outage? In 2017, an outage on Amazon Web Services cost publicly traded companies as much as $150 million. Unfortunately, no company is immune, especially when vital business processes cannot be disrupted. Cloudflare (a major online services provider), Google, Amazon, Shopify, Reddit, Verizon, and Spectrum were among the firms and services that had disruptions in June and July of 2019.

Best practices for minimizing planned downtime in a cloud environment

  • Create services that are high-availability and disaster-recovery ready. Make use of cloud vendors’ multi-availability zones in your infrastructure.
  • Consider multi-region deployments with automated failover if your services have a low tolerance for failure. This will ensure the best possible business continuity.
  • Define and implement a disaster recovery strategy that is aligned with your business goals and provides the shortest recovery time (RTO), and recovery point targets achievable (RPO).
  • Consider using AWS Direct Connect, Azure ExpressRoute, or Google Cloud’s Dedicated Interconnect or Partner Interconnect to provide dedicated access. Between you and the cloud service point of presence, these services provide a dedicated network connection. This can lessen the danger of a company disruption caused by the Internet.
  • Check your Service Level Agreement’s fine print (SLA). Is there a guarantee of 99.9% or better uptime? That 0.1 percent downtime equates to about 45 minutes every month or approximately eight hours per year.

2). Security and privacy

Despite the strongest security standards and industry certifications implemented by cloud service providers, storing data and crucial files on external service providers always poses a risk. Any discussion of data must include security and privacy considerations, especially when dealing with sensitive data. We must not forget what happened at Code Space with the hacking of their AWS EC2 console, which resulted in data loss and the company’s final closure. They had to accept the dangers of outsourcing everything because they relied on remote cloud-based technology.

Of course, any cloud service provider is responsible for managing and safeguarding the deployment’s underlying hardware infrastructure. Your obligations, on the other hand, are in the area of user access control, and it is up to you to carefully consider all risk situations.

Though recent data breaches involving credit card information and user login passwords are still fresh in the public’s consciousness, actions have been made to maintain data security. The General Data Protection Regulation (GDPR), which was recently implemented in the European Union to provide users more control over their data, is one such example. Nonetheless, you must be aware of your duties and adhere to industry best practices.

Best practices for minimizing security and privacy risks

  • This is important: Recognize your cloud provider’s shared responsibility approach. You’ll still be responsible for everything that happens in your network and in your product.
  • Make security a priority at every stage of your deployment.
  • Know who should have access to each resource and service, and give them the least amount of power. If an employee goes rogue and gains access to your deployment, you’d like their impact to be limited to the smallest feasible area.
  • Check to see if your team’s abilities are up to the task. The Top 10 Things Cybersecurity Professionals Need to Know is an excellent post for learning how to address cloud security and privacy concerns.
  • Consider taking a risk-based approach to securing cloud assets and extending security to devices.
  • Multi-factor authentication should be used for all accounts that have access to sensitive data or systems.
  • Encryption, encryption, encryption is the name of the game. Encrypt your data wherever you can – simple wins include object storage like Amazon S3 or Azure Blob Storage, where client data is frequently stored. The simple act of enabling encryption on S3 could have averted the Capital One data breach in July 2019, which exposed the personal information of 100 million customers.

3). Vulnerability to attack

Every component in cloud computing is online, exposing possible risks. Even the best teams are subjected to severe attacks and security breaches on occasion. It’s easy to run before you learn to walk since cloud computing is designed as a public service. After all, no one at a cloud vendor looks over your administrative skills before providing you an account: all you usually need is a valid payment card to get started.

Best practices to help you reduce cloud attacks

  • Make security a top priority in your IT operations.
  • Maintain cloud security best practices across the entire organization.
  • Ensure that security rules and procedures are checked and evaluated on a regular basis.
  • Classify data ahead of time and implement access controls.
  • To automate compliance controls, use cloud services like AWS Inspector, AWS CloudWatch, AWS CloudTrail, and AWS Config.
  • Prevent data espionage.
  • Integrate security operations with preventative and response tactics.
  • Audits can help you find rogue projects.
  • Accounts that don’t need to log in to services should have their passwords removed.
  • Access keys and credentials should be reviewed and rotated on a regular basis.
  • To stay informed about known attacks, keep an eye on security blogs and announcements.
  • If you’re using open-source software, follow security best practices.
  • Encryption should be used whenever and wherever practicable.

These procedures will assist your company in monitoring for critical data exposure and movement, defending key systems against attack and compromise, and authenticating access to infrastructure and data to prevent further threats.

4). Limited control and flexibility

Because the service provider owns, manages, and monitors the cloud infrastructure, the customer has very little influence over it.

Cloud users may find that they have less control over the function and execution of services within a cloud-hosted infrastructure to varying degrees (depending on the service). The end-user licensing agreement (EULA) and management policies of a cloud provider may place restrictions on what customers may do with their deployments. Customers retain control over their apps, data, and services but may not have as much control over their backend infrastructure.

Best practices for maintaining control and flexibility

  • Consider enlisting the help of a cloud provider partner to assist with the implementation, operation, and maintenance of cloud services.
  • To limit the risk of omission or error, understand your responsibilities and the responsibilities of the cloud vendor in the shared responsibility model.
  • Take the time to learn about the basic level of assistance offered by your cloud service provider. Is this service level going to match your support needs? For a fee, most cloud providers give extra support layers in addition to the basic service.
  • Make sure you understand the SLAs for the infrastructure and services you’ll be using, as well as how they’ll affect your customer agreements.

5). Vendor lock-in

Another purported downside of cloud computing is vendor lock-in. Easy switching between cloud services is still a work in progress, and enterprises may find it difficult to transition their services from one vendor to another. Migrating from one cloud platform to another may be difficult due to differences in vendor platforms, which could result in increased expenses and configuration complications. Gaps or compromises made during the migration process could expose your data to new security and privacy risks.

Best practices to decrease dependency.

  • Consider cloud architecture best practices when creating your design. All cloud services offer the possibility of increasing availability and performance, decoupling layers and removing performance bottlenecks. You’re less likely to have troubles transferring your services from one cloud platform to another if you created them utilizing cloud architecture best practices.
  • To avoid lock-in issues, make sure you know what your vendors are selling.
  • To avoid vendor lock-in, use a multi-cloud strategy. While this may add development and operational complexity to your deployments, it isn’t a deal-breaker. Training can assist teams in architecting and selecting the most appropriate services and technology.
  • When creating applications, consider including flexibility as a technique to ensure portability now and in the future.
  • Build your apps using cloud-first features like modularity and mobility of microservices and code. Consider Kubernetes and containers.

6). Cost concerns

Cloud solutions can be seen as costly when used on a small scale and for short-term initiatives. The most major cloud computing benefit, however, is the reduction of IT costs. Pay-as-you-go cloud services can offer greater flexibility and reduced hardware costs, but the total cost may be higher than anticipated. It’s a good idea to try out a number of options until you’re confident about what will work best for you. You can also utilize cost calculators provided by providers such as Amazon Web Services and Google Cloud Platform.

Best practices to reduce costs

  • Instead of over-provisioning your services, consider employing auto-scaling services.
  • Check to see whether you can scale DOWN as well as up.
  • If you have a known minimum use, prepay and take advantage of reserved instances.
  • To save money while your instances aren’t in use, automate the process of starting and stopping them.
  • To keep track of your cloud spending, set up alerts.
