What is Cloud Computing? Types and Examples


The process of moving applications and other data to the cloud often causes complications. Migration projects frequently take longer than anticipated and go over budget. The issue of workload and data repatriation — moving from the cloud back to a local data center — is often overlooked until unforeseen cost or performance problems arise. These three basic offerings have spawned countless other “as a service” solutions. Part of the challenge involved with cloud computing is sorting through these many offerings and figuring out which ones are the best match for the company.

How the cloud connects business processes

Not only do you skirt the costs and labor concerns that come with deploying your own hardware, but you also don’t have to worry about the high upfront costs of software. Plenty of large businesses have also enjoyed the flexibility and agility afforded by SaaS solutions. In summary, nobody in your organization has to worry about managing software updates, because your software is always up to date. Some businesses use IaaS as part of their “lift and shift” strategy, wherein they migrate their data and applications to the cloud.

A user can access cloud data or upload data to the cloud from anywhere with an internet connection using any device. CSPs often implement redundant resources to ensure resilient storage and to keep users’ important workloads running — often across multiple global regions. Whether you’re looking to work in cloud computing or simply want to increase your knowledge on the subject, be sure to check out our other cloud computing resources. Along with the primary cloud service types, there are three primary cloud deployment models.

PaaS shares some similarities with SaaS, the primary difference being that instead of delivering software online, it is actually a platform for creating software that is delivered via the Internet. Services can be both public and private—public services are provided online for a fee while private services are hosted on a network to specific clients. PaaS provides access to a platform within which users can develop and build custom software and applications, said Goldstein. Some pundits took that as an implicit critique of cloud computing. Because the speed and cost of local storage outstrip using a wide-area network connection controlled by a telecom company .

End users can spin up compute resources for almost any type of workload on demand. An end user can provision computing capabilities, such as server time and network storage, eliminating the traditional need for IT administrators to provision and manage compute resources. Companies can build private clouds using their own IT infrastructure.

Security technologies will evolve to become cloud-native and edge-first

Others choose private cloud because their workloads deal with confidential documents, intellectual property, personally identifiable information , medical records, financial data, or other sensitive data. Today, PaaS is often built aroundcontainers, a virtualized compute model one step removed from virtual servers. Containers virtualize the operating system, enabling developers to package the application with only the operating system services it needs to run on any platform, without modification and without need for middleware. In most cases, SaaS users pay a monthly or annual subscription fee; some may offer ‘pay-as-you-go’ pricing based on your actual usage. Cloud computing enables customers to use infrastructure and applications via the internet, without installing and maintaining them on-premises. Cloud computing offers enterprise developers quick access to tools and platforms for building and testing applications, speeding up time to market.

Modern cloud solutions help companies meet the challenges of the digital age.

What are the different types of cloud computing services?

It is the on-demand availability of computer services like servers, data storage, networking, databases, etc. The main purpose of cloud computing is to give access to data centers to many users. Using multiple different vendors, for example, means you get to mix and match features and functionality. If you have a particularly sensitive project, for example, you can run it on a cloud that has extra security features.

What is cloud computing

The vendor also hosts the user’s applications and maintains a backup. Further, cloud can be divided into two different layers, namely, front-end and back-end. The layer with which users interact is called the front-end layer. This layer enables a user to access the data that has been stored in cloud through cloud computing software. Hyperscale data centers can hold thousands of servers and process much more data than an enterprise facility.

Are cloud solutions compliant with data privacy regulations like HIPPA or GDPR?

For most organizations, the promise of trouble-free, cloud-based information systems remains an elusive goal. Although cloud technology is pervasive, today’s installations primarily consist of new applications in private clouds managed by in-house IT staff. The vast majority of enterprise applications and infrastructure still remains on premises, although that is rapidly changing. When a company chooses to “move to the cloud,” it means that its IT infrastructure is stored offsite, at a data center that is maintained by the cloud computing provider. An industry-leading cloud provider has the responsibility for managing the customer’s IT infrastructure, integrating applications, and developing new capabilities and functionality to keep pace with market demands. When we update our status on social media, binge a new streaming series, or check our bank accounts we’re most likely using applications that are hosted by cloud services.

Government Data storage, AI, and analytics solutions for government agencies. Supply Chain and Logistics Digital supply chain solutions built in the cloud. Grid Computing is a middleware to coordinate disparate IT resources across a network, allowing them to function as a whole. The term “Cloud” came from a network design that was used by network engineers to represent the location of various network devices and there inter-connection. Importantly, deployments will extend outside the technology industry, with sectors like healthcare, government agencies, and MSPs gaining from it. Safely stores and protects your data in the event of an outage or crisis.

  • Another would be data storage platforms like Google Drive, Dropbox, OneDrive, or Box.
  • Cloud vendors regularly update security protocols to protect users from cyber threats.
  • Providers have robust methods of securing the cloud and they keep a laser focus on encryption andcloud security.
  • For this reason, the public cloud segment is slated to grow by 18.4% in 2021, reaching a valuation of $304.9 billion as per Gartner estimates.

Most people are likely engaging with cloud-based services in some way throughout their daily lives. With PaaS, developers can focus on the creative side of app development, without having to manage software updates and other infrastructure. Magento Commerce Cloud is an example of PaaS commonly used by e-commerce companies to build and manage custom online stores. If you want to get started in this dynamic field, it’s important to understand the different types of cloud computing and what you can do with them. The prime modern example of a device that is completely cloud-centric is theChromebook.

Organizations have the option to use the appropriate cloud — private or public — for different workloads and applications to optimize cost and efficiency according to the circumstance. Organizations can move certain workloads to or from the cloud — or to different cloud platforms — as desired or automatically for better cost savings or to use new services as they emerge. A community cloud, which is shared by several organizations, supports a particular community that shares the same concerns — e.g., the same mission, policy, security requirements and compliance considerations. A community cloud is either managed by these organizations or a third-party vendor and can be on or off premises. Multi-cloud deployments should become easier, however, as providers’ services and APIs converge and become more standardized through industry initiatives such as the Open Cloud Computing Interface.

Utility Computing Vs Cloud Computing

And of course, from giants like Salesforce down to tiny startups, pretty much every software company is a SaaS company now. Beyond this, the majority also remained worried about the performance of critical apps, and one in three cited this as a reason for not moving some critical applications. And of course, you can only access your applications if you have an internet connection.

Other major cloud providers also support serverless computing capabilities, such as Google Cloud Functions and Azure Functions. A hybrid cloud is a combination of public cloud services and an on-premises private cloud, with orchestration and automation between the two. Companies can run mission-critical workloads or sensitive applications on the private cloud and use the public cloud to handle workload bursts or spikes in demand.

Cloud security refers to the measures undertaken to protect digital assets and data stored on cloud-based services. Measures to protect this data include two-factor authorization , the use of VPNs, security tokens, data encryption, and firewall services, among others. Security has always been a big concern with the cloud especially when it comes to sensitive medical records and financial information. While regulations force cloud computing services to shore up their security and compliance measures, it remains an ongoing issue. Encryption protects vital information, but if that encryption key is lost, the data disappears.

There is also a hybrid option, which combines elements of both the public and private services. Software as a service delivers a full application stack as a service, from underlying infrastructure to maintenance and updates to the app software itself. A SaaS solution is often an end-user application, where both the service and the infrastructure is managed and maintained by the cloud service provider.
