Cloud Computing: An Introduction

by | Oct 3, 2023 | 0 comments

In the IT world there are a lot of terms flying around that we often assume people know what they mean. However, at Sand, we like to empower you with the knowledge you need to understand the concepts of IT and why it is important! We are starting a new series on the basics. Starting with Cloud Computing…after all…knowledge is power.

What is Cloud Computing?

Cloud computing is the delivery of computing services over the internet. These services encompass a wide range of resources, including networking, storage, databases, virtual machines, and have expanded to include cutting-edge technologies like machine learning (ML), artificial intelligence (AI), and the Internet of Things (IoT). Unlike traditional data centers, cloud computing isn’t constrained by physical infrastructure.

With cloud computing, you have the flexibility to choose the computing power and features you need to run your software, but instead of residing on your physical hardware, these resources are hosted in a cloud provider’s data center. This model allows you to pay for only the services you use, while someone else handles the maintenance and upkeep of the underlying hardware.

Key Cloud Computing Services

Each provider offers slightly different services but the most common are compute power and storage:

  • Computer Power: This determines how much processing your virtual machines can perform. You can easily scale up or down your computing power based on your needs, saving you costs by only paying for what you use.
  • Storage: Think of this as the digital equivalent of your hard drive storage. With cloud computing, you can dynamically request more storage as your data requirements grow.

As your business evolves and your computing needs change, cloud computing allows you to quickly and cost-effectively update your IT solutions to accommodate your growth.

Benefits of Using Cloud Services:

When building or deploying a cloud application, there are a few things to consider. For example, its uptime, SLAs, and scalability. Here are some of the main benefits of using cloud services:

  • Scalability: one advantage of cloud computing is the scalability of its resources. Scalability refers to the ability to adjust resources to meet demand. For example, if you suddenly experience a peak and your systems are overwhelmed, the ability to scale means that you can add more resources to handle the increase in demand.
  • Reliability: this is the ability of a system to recover from failures and continue to function. The Cloud, by virtue of its decentralised design, naturally supports a reliable and resilient infrastructure.
  • Predictability: this allows you to move forward with confidence. Performance reliability focuses on predicting the resources needed in order to deliver a positive experience for your customer. Autoscaling, load balancing and high availability are just some of the cloud concepts that are supported by performance predictability.
  • Governance and Compliance: cloud features allow you to set templates to ensure all your deployed resources meet industry and government regulatory requirements. You can also update your resources to meet new standards as they change.
  • Security: you can find a solution that meets you security needs. If you require maximum control or would like automated patches and maintenance, cloud computing has you covered.
  • Manageability: A major benefit of cloud computing is the manageability options. There are 2 types:
    • Management OF the cloud: automatically scale resource deployment, deploy resources based on preconfigured templates, monitor health of resources, and automatically replace failing resources, and automatic alters based on configured metrics.
    • Management IN the cloud: how you manage your cloud environment and resources. Including: Through a web portal or Using APIs.

Now we have explored what cloud services are and highlighted some of its main benefits, lets dig into how it can be used as a powerful tool for SMEs by helping addressing challenges you face.

How can Cloud Computing Benefit you as an SME?

Cloud computing can be a powerful solution for SMEs, addressing various challenges they face, from cost constraints to the need for flexibility, security and competative advantages. Lets dig into the specifics:


  • Reduced Capital Expenditure: SMEs can avoid substantial upfront costs for purchasing and maintaining on-premises hardware. Cloud computing operates on a pay-as-you-go model, allowing businesses to pay only for the resources they use.
  • Scaling Flexibility: SMEs can easily scale their IT resources up or down based on their needs. This agility prevents over-provisioning and reduces wasted resources, ultimately leading to cost savings.

Accessibility and Mobility:

Anywhere, Anytime Access: Cloud services can be accessed from anywhere with an internet connection, enabling remote work and collaboration. This is especially valuable for SMEs with distributed teams or those looking to support flexible work arrangements.
Cross-Platform Compatibility: Cloud applications often support multiple devices and platforms, allowing employees to work on their preferred devices without compatibility issues.

Reliability and Disaster Recovery:

  • High Availability: Cloud providers typically offer robust service-level agreements (SLAs) that guarantee high availability and uptime. SMEs can rely on cloud infrastructure for critical business operations.
  • Automatic Backups: Cloud providers often include automated backup and data recovery solutions, reducing the risk of data loss due to hardware failures or disasters.


  • Easy Resource Scaling: SMEs can quickly scale their computing resources to handle increased workloads or seasonal demands without the need for major infrastructure changes.

Security and Compliance:

  • Advanced Security Features: Many cloud providers offer robust security measures, including encryption, authentication, and access controls. SMEs can benefit from these features without having to invest heavily in security infrastructure.
  • Compliance Assistance: At Sand, we offer compliance certifications, such as CyberEssentials and other tools to help SMEs meet industry-specific and regulatory compliance requirements.

Competitive Advantage:

  • Access to Advanced Technologies: Cloud services often include access to cutting-edge technologies such as machine learning, artificial intelligence, and big data analytics. SMEs can leverage these technologies to gain a competitive edge.
  • Faster Time-to-Market: Cloud computing accelerates development and deployment cycles, allowing SMEs to bring new products and services to market more quickly.

Resource Management:

  • Resource Monitoring and Optimisation: Cloud platforms offer tools for tracking resource usage, enabling SMEs to optimise their IT spend by identifying and eliminating wasteful practices.
  • Automatic Updates: Cloud providers handle software updates and maintenance, ensuring that SMEs are running on the latest and most secure software versions.

Collaboration and Productivity:

  • Collaboration Tools: Cloud-based collaboration tools like email, document sharing, and project management can enhance team productivity and communication.
  • Integration Capabilities: Cloud services often offer integrations with popular business applications, streamlining workflows and improving efficiency.

Support and Expertise:

  • Access to IT Expertise: SMEs can leverage the expertise of cloud providers, like the team here at Sand, and our support teams, reducing the burden on in-house IT staff and ensuring technical issues are resolved promptly.

Environmental Impact:

  • Energy Efficiency: Cloud data centers are often designed with energy efficiency in mind, potentially reducing the carbon footprint of SMEs compared to maintaining their own data centers.

By adopting cloud services strategically, SMEs can unlock significant benefits and focus on growing their core business rather than managing complex IT infrastructure.
