Cloud Computing Deployment Models and Architectures

This gives enterprises a great deal of flexibility and relieves the burden of capacity planning. Users that save information in the cloud can access it using any device and any internet-connected location. Users no longer need to carry along many CDs, USB drives, or external hard drives in order to access their data. Smartphones and other mobile devices can be used to access company data, allowing remote employees to stay in touch with coworkers and clients. The cloud makes it simple for end users to process, store, retrieve, and restore resources.

Examples of SaaS vendor services include Google Docs, Google Gmail and Microsoft Office 365. DefinitionCloud computing, also known as on-demand computing, is a form of internet-based computing that allows end users to share information and resources. The public cloud is owned and operated by large cloud service providers as a geographically distributed, global, often shared IT infrastructure, with logical separations for secure multi-tenancy. By now you are probably thinking, “So what is the difference between hybrid and multi-cloud? ” Well, a hybrid cloud refers to the pairing of both private and public clouds.

Another frequent interdependence of cloud costs is the way that one cloud service frequently makes use of one or more additional cloud services, all of which are included in the regular monthly charge. The biggest cloud solutions and services problem with cloud computing is frequently regarded as security. Organizations that rely on the cloud run the risk of data breaches, API and interface hacks, compromised passwords, and authentication problems.

Checking if the site connection is secure

This model is the most exposed and as such has a variety of inherent security risks that need to be considered. The amount of resources exposed over a network can depend on the type of service that a vendor is providing to its customers. Different services give rise to different security concerns, and may even lead to different parties being responsible for handling said concerns. SaaS is a software-as-a-service distribution paradigm that delivers software programs via the internet; these applications are sometimes referred to as web services.

Provider companies offer resources as a service both free of charge or on a pay-per-use basis via the Internet connection. A community cloud is basically a multi-tenant hosting platform that usually involves similar industries and complimentary businesses with shared goals all using the same hardware. By sharing the infrastructure between multiple companies, community cloud installations are able to save their members money. Data is still segmented and kept private, except in areas where shared access is agreed upon and configured.

The hardware and software components required for the correct deployment of a cloud computing architecture are referred to as cloud infrastructure. Cloud computing is also known as utility computing and on-demand computing. Cloud computing can be private or public, but the goal is always to give simple, scalable access to computer resources and IT services. A cloud deployment is an installation of hardware and software that is accessible over the internet on a specialized platform. We can think of Software as a Service , Platform as a Service , Infrastructure as a Service , and other solutions as being good examples of this. Each of these different solutions are offered to end users, businesses, and other providers so that they can perform specific tasks.

Cloud Computing Deployment Models

Flexibility.One of the best features of this cloud type is that it is very flexible. You can pick the best parts of each cloud type and integrate it into your solution. Rarity.This model is not widely used, yet, so there are not too many resources available for people to learn from or well known examples.

With a hybrid solution, you may host the app in a safe environment while taking advantage of the public cloud’s cost savings. Organizations can move data and applications between different clouds using a combination of two or more cloud deployment methods, depending on their needs. Figure 1 is a brief overview of the various layers involved in the provision of a cloud computing service.

Benefits of Public Cloud Deployments

The public cloud, powered by Intel, gives you additional capacity to speed your innovation. Secure Socket Layer 128 bit encryption – it is a commonly-used protocol for managing the security of a message transmission on the Internet and it uses public and private key encryption system . C. Integrity The integrity of data refers to the confidence that the data stored in the cloud is not altered in any way by unauthorized parties when it’s being retrieved, i.e. you get out what you put in. To ensure this, CSPs must make sure that no third party has access to data in transit or data in storage. Data Security RisksThere are a variety of data security risks that we need to take into account.

In most cases, people referring to Software as a Service are referring to end-user applications. With a SaaS offering you do not have to think about how the service is maintained or how the underlying infrastructure is managed; you only need to think about how you will use that particular piece of software. Back to our analogy, a hybrid cloud deployment model is comparable to renting a vehicle to go somewhere.

A private cloud is hosted in your data center and maintained by your IT team. Because your organization purchases and installs the hardware, this involves a substantial capital expenditure. However, running workloads on a private cloud can deliver a lower TCO as you deliver more computing power with less physical hardware. It also gives you support for legacy applications that cannot be moved to the public cloud. The first cloud computing we’re going to talk about is private cloud computing. This cloud deployment model provides dedicated use to your company’s data and systems over a private IT infrastructure.

The service is provided by the vendor free of charge and on the basis of pay-per-use license policy. The multi-cloud model uses public clouds from multiple providers such as Azure, AWS, or Google Cloud Platform. This method helps create redundancy so that the resources are available in the event of an attack or data loss. Since hybrid architectures have access to both traditional and public cloud resources, they have a lot more flexibility to meet the traditional and new business requirements. Many enterprise customers who are starting to consume public cloud IT solutions as they continue to use their existing on-prem IT environments are driving the popularity of the hybrid cloud architecture model.

Platform as a service (PaaS)

Let us compare this to the security challenges facing the typical CSC, illustrated in figure 3. The Hybrid Cloud Model is a hybrid of public and private cloud computing resources. Serverless computing, which overlaps with PaaS, focuses on developing app functionality without having to constantly manage the servers and infrastructure required to do it. The setup, capacity planning, and server management are handled by the cloud provider. Serverless architectures are extremely scalable and event-driven, consuming resources only when a specific function is triggered. It might be difficult to specify and forecast ultimate expenses when using pay-as-you-go cloud subscription plans and scaling resources to meet changing workload demands.

  • In this post, I will give you a walk-through of Cloud Computing Deployment models.
  • Privacy and data segmentation is a very real concern for many organizations.
  • Private clouds are more expensive than public clouds due to the capital expenditure involved in acquiring and maintaining them.
  • As mentioned earlier, we will limit the scope of our security survey to the most ubiquitous of clouds – the public cloud.
  • There is little to no difference between a public and a private model from the technical point of view, as their architectures are very similar.
  • Hybrid Cloud is another cloud computing type, which is integrated, i.e., it can be a combination of two or more cloud servers, i.e., private, public or community combined as one architecture, but remain individual entities.
  • The two sub keys are generated at both the transmission and receiving ends.

There are many factors pushing organizations toward the cloud, as well as many factors that are keeping organizations away. Each organization must evaluate cloud offerings for itself to see what best fits its needs. For the migration to a CSP under consideration that a remigration to another IT-Service provisioning must be possible, a Five-Phase-Model of secure cloud migration is introduced. RSA – A cryptographic algorithm whose encryption key is public and differs from the decryption key which is kept secret . RSA stands for Ron Rivest, Adi Shamir and Leonard Adleman, the creators of the algorithm. This algorithm is based on the fact that finding the factors of an integer is hard.

Less control.You are not in control of the systems that host your business applications. In the unlikely event that a public cloud platform fails, you do not have access to ensure continuity as would be the case with a traditional server room or data center environment. Understanding the cloud deployment model that is right for your organization will help determine your success in the cloud. There are three basic methods of cloud computing to choose from, so let’s review each of them. For securing your database, private clouds can be considered best as all those within your company/organization have authority to access the private cloud which is secured using a firewall and network level security. The private cloud deployment model is a dedicated environment for one user .

Public Cloud

Our commitment to the cloud service provider ecosystem, continued optimizations, and contributions to the open source community ensure you have broad support and choice when building or buying cloud services. Additionally, you can find a variety of Intel® Select Solutions from our partners for fast and easy deployment. Application compatibility and performance are major considerations with hybrid cloud and multicloud approaches. From this paper, we have gained a decent understanding of cloud computing and what it entails.

Cloud Computing Deployment Models and Architectures

Now that you understand what the public cloud could offer you, of course, you are keen to know what a private cloud can do. Companies that look for cost efficiency and greater control over data & resources will find the private cloud a more suitable choice. Read on as we cover the various cloud computing deployment and service models to help discover the best choice for your business. You can mix and match the best features of each cloud provider’s services to suit the demands of your apps, workloads, and business by choosing different cloud providers.

Our Services

The services can be availed from any part of the world at a minimal per-month fee. Security – Segmentation of resources within the same Infrastructure can help with better access and higher levels of security. No Infrastructure Management – This does not require an in-house team to utilize the public cloud. There are service and licensing limitations because users are offered only general services that are insufficient for complex IT tasks. Cloud Computing providers promise 99.99% availability of your infrastructure. The termination phase is necessary under the consideration that the rollback to internal IT-Service provisioning or the change of the CSP usually is not under consideration by a cloud customer in long-term planning.

It provides higher control over system configuration according to the company’s requirements. Start assessing your needs and consider what type of support your application requires. Blog Your journey towards a cloud that truly works for you can start here. Our blog features technical, educational, and thought leadership pieces that will help you on your path to the cloudeBook Optimize your cloud costs to a whole new level. PaaS extends the abstraction of the underlying infrastructure all the way up to the operating system level for the end users. Software as a Service is provided over the internet and requires no prior installation.

These include items such as your networking bandwidth, computational capabilities and data storage. We’ll look at the outlined deployment types as well as key details that you need to be aware of, and hopefully help you to figure which cloud deployment model is best for you. A public cloud deployment model is a popular choice, especially with providers like AWS, Microsoft Azure, and Google Cloud Platform making a public cloud model extremely accessible and still secure. As the name suggests public clouds are provided by an authorized service provider for general public under a utility based pay-per-use consumption model. This is the most basic type of deployment model in which the services of cloud i.e SaaS, PaaS and SaaS are delivered over a network that is open for public usage. An organization that uses a multi-cloud model incorporates public cloud services from over one cloud service provider.
