Advantages of cloud computing: advantages and disadvantages


Everyone knows the differences between using software hosted on a corporate or home server and subscribing to that same software through a cloud service, right? Maybe, but maybe not; sometimes there is a gray area connecting them, and a user may know some of the differences, but they are more likely not to know all of them.

Like a good baseball player who does extra reps on the field and practices batting every day, we all need to go back and revisit the fundamentals every now and then. So we’re bringing you these cloud facts in this article, and they’re just as important to seasoned veterans as they are to newbies. Hope we include the most important facts to help you with questions regarding your own use cases.

Benefits of cloud computing:


Globally

Cloud computing lowers the costs of IT operations because the cloud provider manages the underlying infrastructure, including hardware and software. These managed components are generally more reliable and secure than the standard enterprise data center because it is the core business of the vendor. These benefits allow IT teams to focus on the work that most directly benefits the business.

The cloud is also global, convenient, highly scalable and accessible, which accelerates the time of creation and deployment of software applications. It opens organizations up to a host of newer services that enable the most popular trends in application architectures and uses, including microservices, containers, serverless computing, machine learning, l large-scale data analysis, IoT, etc.


Unlimited storage capacity

  • No matter which cloud you use, you can buy all the storage you could possibly need, and it’s much cheaper than having to periodically buy new storage hardware and software. Just be aware of the provider’s rules when adding files and removing them.

Automated file and data backup / restore

  • Cloud backup is a service in which data and applications on a company’s servers are backed up and stored on a remote server. Businesses choose to back up to the cloud to keep files and data readily available in the event of a system crash, outage, or natural disaster. Users can also do this on private or corporate servers, but cloud service providers do it as standard 24/7 practice, and users don’t have to think about it.

Less administrative or management hassle

Subscription model easier to manage than an entire system

  • Users receive a monthly invoice; pay it, and you’re good. Gone are the days of buying and managing applications, storage arrays, software and security.

Improved collaboration and mobility

  • Users can access their apps, data and files from anywhere on the planet and on any device, provided they have a good secure internet connection. The cloud has disconnected the world.

Disadvantages of cloud computing:


Globally

While IT teams reduce their capital expenditures with cloud computing because they don’t buy hardware and software, they also add sizable operating expenses to their budgets, often enough to make up most or most of them. all of their operational savings. Complex pricing and security models can also cause major problems if IT teams are unable to adapt. IT teams often need to learn new skills or hire employees to navigate the cloud, and there is limited flexibility and control over some cloud resources.


Dependent on an internet connection at all times

  • While most connectivity providers produce 99.99% uptime or are practically bankrupt, there is still a possibility that a natural disaster, a billing issue, a broken line due to local construction or a similar activity, or a larger regional outage will shut you down and stop you cold in whatever online business you do. While hackers causing chaos in interconnected data centers are rare, this kind of large-scale problem could arise as well. Better to make sure you have a backup access point (or personal storage backup hardware) if you are working from home.

Files are easy to store but not as easy to retrieve and download

  • When working with files, images, videos, data logs, and other objects stored in a cloud, make sure you understand the input and output rules and limitations. Virtual Private Cloud (VPC) service controls have a number of ingress and egress rules to allow access to and from the resources and clients protected by the service perimeters. For example, Google Cloud Platform’s storage entry and exit rules are quite extensive and explain a long list of subtopics, including policy templates, sample API requests, and more. An overview of Google’s VPC service controls can be found here.

  • Likewise, Amazon Web Services has its set of VPC rules just like Microsoft Azure. Failure to understand these rules can result in wasted time and effort for the user or the business.

Cloud management can be complicated to monitor

  • Cloud computing management raises many information systems management issues, including ethical issues (security, availability, confidentiality and confidentiality), legal and jurisdictional issues, data lockdowns, lack of level agreements service standards (SLAs) and technological bottlenecks for personalization, and the like.

Technological vulnerabilities, especially in shared environments

  • There are some associated risks associated with sharing a cloud provider. The most common cloud security issues include unauthorized access through improper access controls and the misuse of employee credentials. According to industry surveys, unauthorized access and insecure APIs are tied for first place as the biggest perceived security vulnerability in the cloud. Others include Internet Protocol vulnerabilities, data recovery vulnerability, metering, billing evasion, vendor security risks, compliance and legal risks, and availability risks.

Data loss or theft and data leakage

  • When you store files and data on someone else’s server, you are handing over your crown jewels to the provider. Whether in a cloud or on a private server, data loss refers to the unwanted deletion of sensitive information, either due to an information system error or theft by cybercriminals. Data breaches are unauthorized exposures of sensitive information through vulnerabilities in the digital landscape. Data leakage threats typically occur through the web and email, but they can also occur through mobile data storage devices, such as optical media, USB drives, and laptops. Data loss occurs when data is accidentally deleted or something causes data corruption. Viruses, physical damage, or formatting errors can make data unreadable by both humans and software. In other cases, lost files and information cannot be recovered, making data loss prevention an essential tool.

Denial of service attacks

  • A denial of service (DoS) attack is an attack intended to shut down a machine or a network, making it inaccessible to the users for whom it is intended. DoS attacks accomplish this by flooding the target with traffic or sending information that triggers a crash. Cloud service users have little or no control over DoS attacks; this again illustrates the importance of safeguarding personal data.

Cloud Computing FAQs

Are cloud computing and software as a service the same thing?

SaaS started the transition to cloud computing by demonstrating that IT services can be made available, secure and efficient on the web. While SaaS providers didn’t originally use the word “cloud” to describe their offerings, analysts now see SaaS as one of the many subsets of the cloud computing market.

Although the cloud was preceded in the late 1990s by application service providers, which were typically single-use providers with fragile connections and poor security, AWS is generally credited with starting the era. from the cloud in the fall of 2006 with the release of its simple storage service. , or S3.

What are the types of cloud?

Private clouds are delimited workspaces hosted in a corporate data center or colocation facility. They don’t have the massive scale of public clouds, but they do have elasticity, and developers and administrators in an enterprise can still use self-service portals to access resources. In theory, private clouds offer more control and security, although it’s up to the company’s IT team to make sure that happens.

Public clouds, such as AWS and Azure, and private clouds can be linked to create a hybrid cloud, or two or more public clouds can be connected to create a multicloud architecture.

What types of applications can run in the cloud?

Technically, users can put any application in the cloud. IDC research indicates that the primary uses of the cloud are for IT management, collaboration, personal and business applications, application development and deployment, and server and storage capacity.

What types of services and applications are considered cloud services?

Some well-known examples of cloud services include Microsoft 365, Zoom, Webex, Facebook, Instagram, Gmail, Skydrive, Google Apps, YouTube, Dropbox, and Box.

What is the bursting of clouds?

The cloud burst is about hybrid clouds. The idea is that a given application typically runs in a private cloud or on-premises computing environment. If a situation arises where the application needs additional resources (computing power, storage, etc.), it can “burst” into the public cloud and use cloud computing for those additional resources. Of course, this can add complexity to the design of the application. Some vendors offer hybrid cloud solutions that make it easier to operate cloud bursting.
