An Introduction to Cloud Computing Infrastructure
Cloud calculating infrastructure has get the modus operandi for an increasing number of companies, including enterprises like Netflix, Upper-case letter One, and Coca-Cola. Many of these companies are replacing their traditional data centers and enterprise deployments of software with cloud based services.
But what nigh this approach is so enticing? And what benefits does information technology offering? What is the difference betwixt cloud computing infrastructure and cloud calculating architecture? All smashing questions. This post volition embrace the following topics to help you better understand why cloud computing infrastructure is and so popular.

What is deject computing?
Cloud computing infrastructure can be defined as the hardware, virtualization, storage, and network components needed to evangelize on-demand computing services. Cloud computing provides the flexibility to merely pay for what you need (cue the Freedom Mutual jingle) at a given moment in time. Consumers and businesses can "rent" It resource instead of owning and maintaining entire physical data centers.
The thought of sharing resources dates dorsum farther than you might recollect. The fundamental practices that led to cloud computing infrastructure engagement back over seventy years agone.
Cloud computing infrastructure vs. cloud computing architecture
Hardware, storage, networking, and virtualization are all fundamental components of cloud computing infrastructure. Information technology'south helpful to remember of them equally the materials needed for a construction projection. A cloud computing architecture is the pattern for how those materials are integrated to build cloud deployment models.
A brief history of cloud computing
The exact origin and common use of the term "cloud" is difficult to pinpoint, but by the 1990'south, it was being used to symbolize a network of undefined and space number of endpoints, or the empty space betwixt a user and a provider.
The origin of cloud computing concepts get as far back as the 1950s, when computers were so massive and expensive that companies had to create "fourth dimension-sharing" schedules. Multiple users could admission mainframes from remote workstations, called "impaired terminals," with no processing power.
In the 1960'south, MIT developed a primitive cloud using reels of magnetic tape for a war machine project chosen DARPA (the Defense Advanced Research Projects Agency). Just two to three people could access this early cloud surround simultaneously. This marks the beginning of virtualization, one of the central components of cloud computing infrastructure, although its definition has since been broadened. A few years laters, J.C.R Licklider helped shape another component of deject calculating infrastructure through his vision of a Galactic Network.
How does cloud computing work?
And at present, the moment you've been waiting for--deject computing explained! Cloud computing is made practical by virtualization, which separates the physical hardware, network, and location for storage into virtual resource pools that tin be accessed remotely. Rather than owning all of the infrastructure and the administration overhead, businesses tin can charter resources that meet their needs. This flexibility allows users to purchase the industry's all-time cloud computing services (since they are constantly evolving), without the upfront or long term cost of owning and maintaining the infrastructure.
Permit's take a await at the components of cloud computing infrastructure: hardware, storage, network, and virtualization.
Iv components of cloud calculating infrastructure
Hardware
While corporations may exist moving abroad from beingness "hardware companies", each owning big data centers to see their needs, the back-stop equipment is yet needed to actually "compute" the workloads. The owners of data centers have transitioned to cloud providers like Amazon, Microsoft, IBM and Google, who each own over 50 data centers (according to IEEE ComSoc report).
Hither is but a small list of some of the hardware that is needed in each of these geographical data centers to brand cloud computing infrastructure possible:
- Servers, processors, and memory
- Network switches, routers, and cables
- Firewalls and load balancers
- Cooling systems
- Power supplies
Storage
Cloud computing infrastructure provides data retention through three prevalent storage types: file, object and block. Each one is ideal for unlike use cases—let'due south examine farther.
File storage allows for data to be collected into a unmarried piece of information and presented in hierarchical convenient file folders.
Object storage is used for large quantities of unstructured static data. It has three parts: the raw data every bit a distinct unit chosen an object, metadata used to give context to the object, and a globally unique identifier. Object storage in cloud computing is oftentimes used for media files and archived data that needs to scale but not exist edited.
Block storage is appropriate when depression latency operations and high functioning workloads are needed within cloud computing. Files are broken down into "blocks" of information and a unique identifier, but no metadata is stored. Data can be stored across multiple locations and environments and tin be hands recovered if there is a hardware failure.
| Utilize Case | Advantages | |
| File Storage | File storage, local archiving, and data protection | Easy to organize files in an hierarchy |
| Cake Storage | Databases, mission critical apps, and RAID (redundant array of independent disks) volumes | Low latency and high I/O (input/output) operation |
| Object | Web apps, big data sets, and backup archives | Cost constructive extremely scalable |
Network
A cloud computing infrastructure would non be consummate without access to back-stop resources. A network, composed of physical hardware similar routers, switches, and high-speed cable are the foundation for which the virtual networks operate.
Cloud computing infrastructure providers like Amazon, Google and Microsoft provide an brainchild from the physical network configuration by creating virtual local area networks (VLANs) and virtual private networks (VPNs). Administrators have the flexibility to define what traffic is sent over private networks (on-premise and private deject), public cloud and multi-deject deployments.
Virtualization
Virtualization is a software engineering science that makes the computing services independent from the physical infrastructure through brainchild. While virtualization and cloud computing are often used interchangeably, they are quite different. The former is the underlying engineering science that makes resources "virtual", while the latter is the delivery of the shared services so they are automated, scalable and cocky-serviced.
Benefits of cloud infrastructure
Cost savings
Companies can reduce operating expenses by avoiding upfront costs that come with purchasing hardware and software. Simply put, cloud computing infrastructure allows the user to only pay for what they need.
Reliability
Cloud providers take redundant availability zones designed for loftier availability, fault tolerance, and scalability; this calibration is far greater than what most companies tin can implement themselves.
Disaster recovery
It might non be possible to prevent all potential disaster scenarios, but you tin can take advantage of numerous redundant and recovery capabilities in the deject to minimize any downtime caused by disk or hardware problems, power outages, or man error.
Flexibility
With cloud computing infrastructure, you gain the flexibility to choose the best technologies in software, platforms and calculating resources.
Scalability
Cloud computing infrastructure can grow or shrink hands and rapidly. If your business experiences a burst of traffic you can quickly scale upwards to run into the need. On premise you might exist waiting for a shipment to arrive before you can scale!
Security
Deject providers can provide security through scale and standardization across their deject computing infrastructure.
Limitations of cloud infrastructure
Migrating to the cloud tin have some limitations that are not always obvious. Let's review some of the primary disadvantages of using cloud computing infrastructure:
Express control
Utilizing a managed set of cloud calculating services is platonic for scalability and cost savings, merely that comes at a price in the form of control. Since cloud computing infrastructure is hosted past the cloud service provider, customers volition have limited control over the administrative controls and no direct access to the backend infrastructure. Typically, this is not an issue for most companies, but something that should exist considered.
Dependant on Net connectivity
Many of us take internet access for granted, simply a network outage or slow net speed will affect the quality of the services from the cloud provider. If y'all feel a loss of internet access you will be unable to have advantage of any of the hosted resource.
Security
Yep, this was listed as an advantage, but tin can also exist a limitation if not properly configured. When you deploy workloads to the cloud, you are relying on the deject provider to provide overall security of the platform, but you lot are however responsible for securing your own applications, implementing best practices, and enforcing deject governance policies.
Types of cloud computing services
According to Gartner's latest written report, public deject end-user spending is expected to exceed 480 Billion in 2022. Let's accept a await at the 3 most common deject computing layers offered on public cloud computing infrastructure:
Software as a service (SaaS)
SaaS is the most ordinarily used type of cloud service and is delivered to the stop user as a consummate application. The operating organisation and underlying deject calculating infrastructure used to host the software is hidden from the user. Familiar examples of a SaaS solution include Dropbox, Cisco WebEx, Salesforce, and Google Thou Suite.
Platform equally service (PaaS)
PaaS is a gear up of services that provide a framework for creating, running, and managing business applications. This service is pop with developers since information technology allows them to focus on writing code rather than managing the runtime environment, operating systems, and middleware. Microsoft Azure, OpenShift, and AWS Elastic Beanstalk are mutual examples.
Infrastructure as a service (IaaS)
Iaas is an aggregate of deject computing infrastructure in the course of virtualized computing resources. Rather than purchasing and maintaining hardware on-premises, companies tin can order virtual servers, databases, storage and networking services on-need. Amazon Web Services (AWS), Google Compute Engine (GCE), and IBM Deject are merely a few examples.
Public, individual, hybrid and multi-cloud deployments
Deject computing infrastructure components remain the same across the four common deject deployment models. Each delivers cloud computing shared resource to the consumer through virtualization of the concrete hardware, storage and networking. Let's take a look at what makes them different.
Public cloud
Public clouds are managed past a 3rd party and are available over the internet. Their resources are self-service and made available on-demand; this allows consumers to scale without the upfront cost of maintaining their own deject calculating infrastructure. Customers are accountable for securing the applications they deploy while the deject provider is responsible for securing the deject computing infrastructure. There are enough of public deject options, and most offer free cloud computing resource to get started. This is an platonic option for customers that are looking for a low-maintenance, low-cost, and a scalable solution.
When migrating to a public deject deployment model you are not express to a unmarried cloud computing infrastructure provider. If a company wants to have advantage of manufacture leading cloud technologies, using multiple public cloud providers (multi-cloud) provides some flexibility in selection and could potentially reduce cost if applications are containerized and portable.
Private cloud
In a individual cloud deployment, the cloud calculating infrastructure can either be deployed on-premise or 3rd political party hosted; dedicating access in either case to a unmarried company. Companies have total control on where information is stored and how the networks will be routed. This is ideal for companies that want to maintain the security of an isolated environs and have more than granular customization control while even so providing the advantages of cloud calculating. This additional control has its disadvantages since information technology could be more expensive and may not exist as scalable as public deject.
Hybrid cloud
A hybrid deject computing compages utilizes deject calculating infrastructure from both a individual and public deject. The flexibility of this deployment model allows the company to determine which applications and services should be kept within their firewall for maximum security and workloads can take advantage of the price savings of public cloud calculating. Companies that are considering a full move to the public deject will often implement a hybrid cloud solution initially.
Wrapping up cloud infrastructure
To summarize, cloud calculating infrastructure are the components necessary to implement cloud calculating. Technology breakthroughs over the last seventy years have fabricated it possible for on-demand resources to be shared over the internet. With a variety of deployment and cloud services to cull from, depression upfront costs, and industry leading technologies bachelor it is not a question of "if" a company will eventually adopt a deject infrastructure but "when".
I promise this post was helpful in understanding a niggling more nearly cloud computing infrastructure and how it tin be used in your journey to the cloud. Thanks for reading.
