When it comes to expert cloud solutions, people often confuse the terms cloud computing and cloud infrastructure. That’s why we decided to write this article, which delves into the components, types, and delivery models of cloud infrastructure, and also the difference between cloud computing and cloud infrastructure.
What is cloud infrastructure?
Cloud infrastructure is the combination of hardware and software components that form the foundation for delivering cloud services. It includes servers, storage, networking equipment, and virtualization software, all managed through automation and management tools to provide scalable, flexible, and cost-effective computing resources over the Internet.
Components of cloud infrastructure
Cloud infrastructure comprises several critical components that work together to deliver seamless and efficient cloud services:
1. Servers
Servers are the core of cloud infrastructure, providing the computational power needed to run applications and processes. These can be physical servers located in data centers or virtual machines (VMs) created through virtualization technology.
2. Storage
Cloud storage involves the use of remote servers to store data, which can be accessed and managed over the Internet. This includes various types of storage solutions, such as object storage, block storage, and file storage.
3. Networking
Networking is essential for connecting the various components of cloud infrastructure. It includes routers, switches, and other networking devices that ensure data is transmitted efficiently and securely between servers and storage systems.
4. Virtualization
Virtualization technology enables the creation of virtual instances of servers, storage, and networks. It allows multiple virtual machines to run on a single physical server, maximizing resource utilization and flexibility.
5. Management and automation software
These tools help manage and automate the deployment, configuration, and maintenance of cloud resources. They include orchestration tools, monitoring software, and management consoles.
Thanks to this combination of elements, it is possible to collect and transmit data to the cloud, which is useful for IoT devices that constantly need to gather and process data:
Types of Cloud Infrastructure
Cloud infrastructure can be classified into different types based on deployment models (see Edge computing vs Cloud computing) and resource management:
1. Public cloud
In a public cloud, the infrastructure is owned and operated by a third-party cloud service provider (what are cloud services), and resources are shared among multiple customers. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
2. Private cloud
A private cloud is dedicated to a single organization, offering more control and security over the infrastructure. It can be hosted on-premises or by a third-party provider.
3. Hybrid cloud
A hybrid cloud combines both public and private cloud infrastructures, allowing data and applications to be shared between them. This model provides greater flexibility and optimized resource utilization.
4. Multi-cloud
In a multi-cloud setup, an organization uses multiple cloud service providers to avoid dependency on a single vendor and to leverage the best features of each provider.
Delivery models in cloud architecture
Cloud services are delivered through various models, each catering to different business needs:
1. Infrastructure as a Service (IaaS)
IaaS provides virtualized computing resources over the internet. It includes virtual machines, storage, and networks, allowing businesses to rent these resources on a pay-as-you-go basis. Examples include AWS EC2 and Google Compute Engine.
2. Platform as a Service (PaaS)
PaaS offers a platform for developers to build, deploy, and manage applications without worrying about the underlying infrastructure. It includes tools and services for application development, such as databases and middleware. Examples include AWS Elastic Beanstalk and Google App Engine.
3. Software as a Service (SaaS)
SaaS delivers software applications over the internet on a subscription basis. Users can access these applications through a web browser, eliminating the need for local installation and maintenance. Examples include Microsoft Office 365 and Salesforce.
Cloud Computing vs. cloud infrastructure
Cloud infrastructure is the underlying framework that supports cloud computing (see cloud computing advantages). And the latter encompasses the broader concept of delivering various services over the Internet. Let’s go deeper into each one:
Cloud infrastructure
- Physical and virtual resources (servers, storage, networking, etc.).
- It serves as the foundation for cloud services.
- It can be managed by the user or a third-party provider.
Cloud computing
- Its focus is on the delivery of services (IaaS, PaaS, SaaS) over the internet.
- It needs cloud infrastructure to provide scalable and flexible services.
- It’s also managed by the service provider.
Now that it is clearer to you the definition of cloud infrastructure, you can better choose the different options for your IoT project.
