Resource Usage Optimization
Cloud computing infrastructure comes with tools for monitoring and optimizing resource usage. In most cases, on-premises infrastructure often doesn’t offer this resource usage optimization.
Cloud computing is ideal for businesses that need multiple locations to serve customers worldwide with low latency. On-premises infrastructure to serve a similar global audience can be cost-prohibitive.
These advantages collectively make cloud computing a powerful solution for businesses seeking agility, cost-effectiveness, and the ability to stay ahead in a rapidly evolving technological landscape.
How Does Cloud Infrastructure Contribute to Cloud Computing?
Cloud infrastructure forms the foundation of cloud computing by breaking down the functionalities and attributes of physical hardware and software components. Subsequently, a cloud service provider, or in the case of a private cloud, the organization’s IT department, oversees these virtualized resources and dispenses them to users via the internet or a network.
These resources encompass virtual machines (VMs) and elements like servers, in-memory computing components, network switches, firewalls, load balancers, and storage. These resources frequently facilitate delivering specialized services, including artificial intelligence (AI) and machine learning.
What Does Cloud Computing Infrastructure Include?
With the question of ‘what is cloud computing infrastructure’ addressed, let’s explore the composition of this infrastructure and the interaction among its components.
Cloud computing infrastructure serves as the foundation for the digital transformation of businesses worldwide. It’s a dynamic ecosystem composed of several key cloud infrastructure components, each playing a pivotal role in cloud services’ seamless functioning and delivery. Let’s dive into the details of these components to understand their significance:
Prominent public cloud providers, like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform, offer services based on shared, multi-tenant servers.
This approach ensures substantial computational capabilities to manage unpredictable shifts in user requirements effectively and efficiently distribute demand across a cluster of servers. Consequently, cloud infrastructure primarily comprises high-density systems that utilize the shared capabilities of servers to deliver multi-socket and multicore services.
Unlike most conventional data center setups, cloud infrastructure commonly employs locally connected SSD and HDD storage solutions. These solutions often differ from the shared disk arrays within a storage area network.
These persistent storage systems are consolidated through a distributed file system (DFS) tailored explicitly for specific storage scenarios, such as big data, block storage, and objects.
The storage infrastructure brings streamlined scalability by separating storage control and management from the physical components through a distributed file system. Cloud providers can match capacity with user workloads by adding compute nodes with storage components instead of deploying large storage chassis in bulk.
Cloud computing relies on robust, high-bandwidth connectivity to facilitate seamless data transmission across the infrastructure. Generally, the network infrastructure comprises standard local networks based on switches and routers. Additionally, it integrates virtual networking capabilities and load-balancing mechanisms to distribute network traffic effectively.
Virtualization plays a crucial role in cloud computing. It enables the creation of virtual instances (virtual machines or VMs) on a single physical server, allowing multiple workloads to run independently.
This crucial component optimizes resource utilization, making it easier to scale resources up or down as needed. It also enhances disaster recovery capabilities by allowing quick VM backups and data migrations to new instances.
The Difference Between Cloud Computing Infrastructure and Cloud Architecture
The idea of infrastructure in cloud computing refers to all hardware and software components an enterprise needs to move and operate in the cloud. This usually includes cloud computing storage, computing power, essential services, management tools, and storage solutions.
On the other hand, cloud architecture refers to the interconnection of diverse technologies that form a cloud computing environment. This idea is implemented as a collection of components, such as hardware, networking infrastructure, operating systems, virtual resources, automation software, management utilities, and container technologies.
Essential Requirements of Cloud Computing Infrastructure
The success of a business migrating to the cloud depends entirely on the capabilities of the cloud computing infrastructure used for deployment. Since cloud computing infrastructure aims to provide a stable foundation for business processes, getting it right from the start is essential.
A cloud computing IT infrastructure needs to deliver the following to meet this standard:
Clear Service Offering
It’s crucial to define the services clearly. The documentation should outline access and usage restrictions so users can understand what to expect. This simplifies resource planning and budgeting. The businesses can add the necessary resources or scale the cloud infrastructure to accommodate increasing user requirements.
Integration With Providers
While cloud computing is entirely virtual, the business needs physical integration with the cloud infrastructure provider. Certain business functions, such as billing, deployment, and application management, require connections through proprietary APIs.
Reporting level and accuracy are crucial for operating and maintaining cloud computing infrastructure. Tracking system performance is vital to ensuring quality customer service, billing, and compliance.
Comparison: Public vs. Private vs. Hybrid Cloud Computing Architecture
Cloud users can either have dedicated access to the cloud infrastructure or share the infrastructure with other users. However, in most cases, the infrastructure they use combines both options.
In practice, a business can opt to adopt one of the following three cloud computing architecture deployment models:
- Public Cloud: Multiple users share this multi-tenant, third-party-owned cloud environment. Public cloud services are a great way of leveraging economies of scale and lowering the cost of data storage and computing. The users generally pay for the services regularly.
- Private Cloud: A private cloud infrastructure is a single-user option with exclusive access to all resources. Usually, businesses with higher transaction volume, security, or data privacy requirements use exclusive single-tenant infrastructure offered by private cloud providers.
- Hybrid Cloud: This cloud computing infrastructure is a mix of public and private models that interact with each other through separate but interconnected systems. An enterprise may use a private cloud to maintain privacy for sensitive applications and a public cloud to expand its capacity or enhance flexibility.
What are the Various Types of Cloud Computing Delivery Models?
Cloud computing services offer three distinct cloud delivery models that reflect the varying combinations of resource access and provisioning levels.
Infrastructure as a Service (IaaS)
In the Infrastructure as a Service (IaaS) model, organizations tap into cloud infrastructure elements as resources and services accessible via a dedicated internet connection. Businesses use the IaaS model to leverage cloud computing capabilities without spending a significant monthly budget on maintaining on-premises infrastructure.
Providers offer specialized services beyond basic cloud infrastructure, such as container infrastructure, service fabrics, serverless functions, and managed network services such as virtual private clouds, load balancers, domain name services, and firewalls.
IaaS pricing generally follows a metered approach, aligning rates with usage levels and performance benchmarks. Examples include standardized virtual CPU sizes with corresponding memory, storage options (object or block), and capacity measured by usage over time.
Platform as a Service (PaaS)
The lines between IaaS and Platform as a Service (PaaS) have recently blurred. PaaS builds additional layers upon infrastructure resources, introducing capabilities like load balancing, autoscaling, application development frameworks, and automated deployment mechanisms.
Software as a Service (SaaS)
Unlike the IaaS and PaaS models, customers don’t directly engage with cloud infrastructure-based resources in the Software as a Service (SaaS) delivery model. Instead, the provider hosts and manages applications, typically configured within a multi-tenant architecture. Users access the service via a browser, while data related to the application can be stored locally, in the cloud, or both.
These cloud computing delivery models provide a range of options for businesses seeking to leverage cloud infrastructure’s capabilities.
