what is Cloud infrastructure : generally cloud is classified into three parts that work together to create a cloud service
- Computing: The computing part of the infrastructure is delivered through server racks to provide cloud services for different services and partners.
- Network: to transfer data both externally and between the computer and the storage systems, this part of the infrastructure relies on routers and switches.
- Storage: A cloud infrastructure is likely to require considerable storage, often using a combination of hard drives and flash storage.
Cloud infrastructure vs. SaaS, PaaS and IaaS
In general, there are three models when it comes to cloud services: SaaS (Software as a Service), PaaS (Platform as a Service) and IaaS (Infrastructure as a Service). Each service has different levels of benefits and differences.
SaaS: Software as a Service (also known as cloud application services), is the most widely used type of cloud service. Popular for business, because SaaS companies provide a powerful customer experience through the exchange of information and services, SaaS removes much of the IT burden from the hands of the business. SaaS uses the Internet to provide distributed applications and services, eliminating the need for customers to download any software. With SaaS, one cloud provider fully manages the entire offering: applications, data, runtime, middleware, operating systems, services, storage, networking, and virtualization.
PaaS: Platform as a Service is somewhat comparable to SaaS, but instead offers a platform for creating software. The PaaS method is delivered over the Internet, giving IT teams the ability to design software without worrying about other things. With PaaS, the cloud provider handles most of the service, including runtime, middleware, operating systems, servers, storage, networking, and virtualization. Therefore, the company only has to worry about managing its applications and data.
IaaS – Infrastructure as a Service provides the highest internal control, allowing direct access and maintenance to most cloud resources. IaaS is fully automated and scalable, as customers can purchase resources as needed without relying on internal hardware. With IaaS, cloud services are largely managed by an enterprise, including applications, data, runtime, middleware, and operating systems. But the cloud provider is responsible for services, storage, networking, and virtualization.
The difference between private, public and hybrid cloud architectures
A cloud infrastructure is offered in three methods: private, public, and hybrid. Each offers a different amount of security, control, and management.
Private: With a private cloud architecture, the service is performed internally and on site. Resources are shared internally among closed users for a high level of control and security of sensitive data. This method is often best done when a business is large enough to effectively operate its own cloud data center and has the budget to finance it. A private cloud makes sense, for example, if a company’s business revolves around an application and its data.
Public – A public cloud architecture is a service provided, managed, and maintained off-site over the Internet. This method can help streamline application collaboration and workflows with many users (email, for example), making resource sharing more efficient. However, there is a greater risk of vulnerability with a public offering. A public cloud makes sense, for example, if a company is working on an ad-hoc software development project with a PaaS offering.
Hybrid – A hybrid cloud architecture includes a mix of public and private cloud offerings. This offering provides efficiency with a public cloud and security with a private cloud, but a business must manage multiple platforms simultaneously, while ensuring seamless integration. A hybrid cloud makes more sense, for example, if a business wants to enable a SaaS application while prioritizing security. Therefore, the SaaS provider would create a private cloud on their firewall.
Cloud infrastructure as a service
A cloud-to-service (IaaS) infrastructure, as with all cloud technologies, is accessed over the Internet through the data center of a cloud provider, which is responsible for maintaining and managing traditional local hardware, like servers. and other storage devices, as well as network and display. This means that the customer has the freedom and control to manage applications, data, middleware, and other operating systems.
With an IaaS cloud solution, there are important infrastructure services, such as network monitoring, security, billing, disaster recovery, and load balancing. There are advanced automation techniques and orchestrations to simplify application performance and management, as well as to make it easier to install operating systems, deploy middle ware, launch virtual machines, and create backup storage and workloads.
Cloud infrastructure management
The primary goal of cloud infrastructure management is to ensure business scalability, while strengthening IT resources and allowing a variety of users to share the same infrastructure without compromising each other’s data. In the long term, this reduces operating costs.
A Cloud Infrastructure Management Interface (CIMI) is an open API standard requirement for cloud infrastructure management and enables users to manage it in a simplified way, with seamless communication between cloud ecosystems. Achieve interoperable management between cloud providers, developers, and customers.
Requirements to build a cloud infrastructure
When creating a cloud strategy, you need to take some deep steps to ensure a strong infrastructure.
Requirement 1: Management of resources and services
A cloud infrastructure virtualizes all the components of a data center. Service management is a metered package of applications and services that end users can easily deploy and manage through a private and / or public cloud provider. And a simplified tool for configuring and evaluating services is vital for cloud administrators to commercialize the functionality. Service management should include resource maintenance, resource guarantees, billing cycles, and metered regulations. Once deployed, management services should help create data and workflow policies to ensure that they are fully efficient and that processes are delivered to cloud systems.
Requirement 2: Integration of data center management tools
Most data centers use a variety of IT tools for systems management, security, procurement, customer support, billing, and directories, among others. And they work with cloud management services and open APIs to integrate existing operating, management, maintenance, and provisioning (OAM & P) systems. A modern cloud service must support the existing infrastructure of a data center, as well as use modern software, hardware, virtualization and other technologies.
Requirement 3: Reports, visibility, reliability, warranty.
Data centers need high levels of visibility and real-time reporting capabilities in the cloud to ensure compliance, SLAs, security, billing, and reimbursements. Without robust reporting and visibility, managing system performance, customer service, and other processes is nearly impossible. And to be completely reliable, cloud infrastructures must function independently of one or more faulty components. To protect the cloud, services must ensure that data and applications are secure, while providing access to authorized parties.
Requirement 4: Interfaces for users, administrators and developers
Automated deployment and self-service interfaces facilitate complex cloud services for end users, helping to reduce operational costs and adopt them. Self-service interfaces give customers the ability to efficiently launch a cloud service by virtually managing their own data centers, designing and managing templates, maintaining virtual storage, network resources, and library usage. Admin interfaces provide better visibility of all cloud resources, virtual machines, templates, service offerings, and multiple users. And all these structures are integrated via developer API.
The benefits of using cloud infrastructure
The arguments in favor of using the cloud are getting stronger as technology continues to improve. Therefore, there are some obvious key benefits of migrating to a cloud infrastructure that helps companies optimize business processes.
Cost: First, the cloud eliminates or significantly reduces operating costs for a company that sets up and manages its own data center. This process begins to boost up with all the various hardware, software, servers, bills, experts in IT, and upgrades that come with this multi-faceted setup. With cloud infrastructure, a business simply pays to manage everything and only pays for the services it needs.
Agility and flexibility: Most cloud service infrastructures are self-managed, where service changes can be made in minutes. This improves the up time and efficiency of business systems, while allowing colleagues and external partners to access shared data on mobile devices anywhere, anywhere. And with a cloud infrastructure that manages the processes, a company focuses more on business than IT.
Security: There is a misconception that cloud services are generally not secure and that data can easily be compromised. However, there is some truth to the fact that, however, risks are often disproportionately removed, at least in terms of enterprise-level cloud infrastructure and services. Cloud infrastructure providers and technologies are always improving protection against hackers, viruses, and other data breaches with stronger firewalls, advanced encryption keys, and a hybrid approach that stores sensitive data in a private cloud and other data, even applications, in a public cloud.
Disadvantages of using cloud infrastructure
That said, not all cloud infrastructures are perfect. And while there are many more advantages, there are still some disadvantages.
Change of provider: the cloud is still an evolving technology, although it is improving, fluctuating rapidly. In other words, some cloud service companies understand well and others don’t. If a company goes out of business or sees a massive overhaul, it could be destructive for a company that relies on a single infrastructure for its entire database.
Connection dependency – A cloud infrastructure is only as good as a network connection. Therefore, the cloud cannot stay afloat without a reliable connection. Any failure of an Internet or intranet connection due to a technical outage or storm means the cloud is going down with all the data, software and / or applications on it. A reliable network means that business promises and SLAs are kept.
Control: Because a company’s cloud infrastructure is generally controlled by its service provider, sometimes there are organizations that have limited access to data. And business customers have even less control than they would like, with limited access to applications, data and tools stored on a server.
