A Beginner’s Guide to Cloud Computing

Cloud computing is more than just a technological trend; it’s a transformative shift that offers unparalleled efficiency, scalability, and innovation. But we’re getting ahead of ourselves.

At its core, cloud computing is about using the internet to access and store data, rather than relying solely on a personal computer or local server. This shift in technology is transforming the way businesses operate, offering a range of benefits from cost savings to enhanced collaboration.

If you’re a business owner looking to invest in cloud computing or a beginner wondering how it all works, this guide will break down the various components of cloud services, models, and providers, and highlight key considerations for cloud adoption.

“The Cloud”: What Does That Mean?

Cloud computing might seem like a complex concept, but at its heart, it’s all about sharing and accessing data more efficiently. The cloud works like a vast digital library of computing resources that multiple users can tap into. This centralised system ensures optimal use of resources, reducing waste and redundancy.

The cloud stores resources – digital data of any kind – on remote servers (like a digital storage room), and you can access them via the internet, no matter where you are.

Using the Cloud: What Do I Need?

Internet connection: The primary requirement is a stable internet connection. The speed of this connection will influence how quickly you can access your data or use online applications.

A device: Whether it’s a computer, smartphone, or tablet, you’ll need a device to access the cloud.

Cloud service account: To use specific cloud services, you often need to create an account with a cloud service provider. This account helps secure your data and ensures only authorised users can access it.

Basic software: Sometimes, you might need specific software or apps to access certain cloud services. For example, to use a cloud-based document editor – like Dropbox – you might need to download its app.

Understanding Cloud Models and Services

The cloud allows users to access and store data and applications on remote servers via the internet, rather than on local storage devices or personal computers. This approach contrasts with traditional computing, where data and software are stored on individual devices or local servers. There are primarily three types of cloud services, and several different deployment models, that cater to various needs.

Types of Cloud Services

Infrastructure as a Service (IaaS): This service provides virtualised computing resources over the internet. It offers the infrastructure such as virtual machines, storage, and networking.

Platform as a Service (PaaS): PaaS provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure associated with application development.

Software as a Service (SaaS): With SaaS, software applications are delivered over the internet on a subscription basis. Examples include customer relationship management tools, email services, and collaboration software.

Deployment Models

Public cloud: Services are delivered over the public internet, offered to multiple customers and managed by third-party providers.

Private cloud: This model is used by a single organisation. It can be hosted either on-premises or by a third-party provider.

Hybrid cloud: A combination of public and private clouds, allowing data and applications to be shared between them.

Community cloud: This cloud infrastructure is shared among several organisations with common concerns, such as security requirements or mission objectives.

Major Cloud Service Providers

There are dozens of cloud providers in the marketplace, but these three giants are most popular: Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP). Each offers a comprehensive suite of cloud services but comes with its own unique features and strengths.

Amazon Web Services (AWS)

Launched in 2006, AWS is a subsidiary of Amazon providing on-demand cloud computing platforms. Known for its extensive service offerings, high reliability, and a broad customer base, it has a head start in the market, making it the most mature and robust platform.

Microsoft Azure

Microsoft’s cloud platform Azure is a close competitor to AWS, offering a wide variety of services, including those for computing, analytics, storage, and networking. Its strongest feature is its integration with other Microsoft services (Windows Server, Active Directory, and the Microsoft 365 suite).

Google Cloud Platform (GCP)

As Google’s cloud service offering, GCP specialises in high-compute offerings like big data, analytics, and machine learning. GCP is known for strong offerings in data analytics, open source technologies, and pricing advantages.

Key Benefits of Cloud Computing

Cost savings: Instead of large, upfront investments in hardware and infrastructure, most cloud platforms offer a pay-as-you-go model. This approach eliminates the need for costly equipment, reduces maintenance expenses, and optimises IT staffing costs.

Scalability and flexibility: With cloud computing, businesses can easily adapt to changing workloads. If a company needs additional data storage, the cloud allows for quick scaling up. Conversely, during slower periods, resources can be scaled down. This flexibility ensures that companies only pay for what they use, rather than overcommitting resources.

Accessibility and collaboration: The cloud allows users to access data and applications from virtually anywhere with an internet connection. This accessibility fosters collaboration, especially for teams dispersed across different locations. Multiple team members can work on a single document in real-time, streamlining workflows and enhancing productivity.

Disaster recovery and backup: Traditional recovery methods can be time-consuming and often require manual intervention. In contrast, cloud-based recovery solutions are faster and more reliable. Automated backup processes ensure that data is regularly saved and can be swiftly restored in case of any disruptions or data breaches.

Automatic updates: Staying updated with the latest software versions is crucial for security and performance. Cloud-based applications receive regular and automated updates, ensuring users always have access to the latest features and security patches. This automatic update mechanism reduces the burden on IT teams and ensures a more secure and efficient computing environment.

Cloud Computing Considerations: Key Factors and Concerns

Data security and privacy: Understanding how and where data is stored is crucial for aligning the cloud environment with cyber security solutions and practices. Additionally, ensuring compliance with Australian data protection regulations is essential to avoid fines or legal ramifications.

Downtime and service reliability: No technology is immune to occasional outages, and cloud services are no exception. Before transitioning to the cloud, businesses should be aware of the potential for service downtime. It’s vital to choose a cloud service provider with a strong track record of reliability, and to have contingency plans in place for any interruptions.

Costs over time: Understanding the long-term financial implications will help companies align IT plans with business strategies. Some services might have hidden costs associated with data transfer, premium features, or additional storage. Regularly reviewing and assessing cloud expenses can help to avoid unexpected charges.

Vendor lock-in: Each cloud service provider has its own unique environment, including tools, services, and APIs. This can sometimes make migrating to a different provider in the future challenging. Before committing to a specific provider, businesses should understand the terms of service, potential exit fees, and how easy or difficult it might be to transition services if needed.

Assessing business needs: Understanding specific requirements involves identifying which workloads and data sets are best suited for the cloud, as well as determining the type of cloud service that aligns with operational needs. A thorough assessment will ensure smooth transition and maximise the benefits of cloud adoption.

User training and skill development: Cloud computing might introduce new tools and platforms unfamiliar to the existing workforce. As such, investing in training is essential to ensure that staff can effectively use and navigate the new cloud-based environment. Continuous learning initiatives can also be set up to keep the team updated with any changes or advancements in the cloud sector.
