5 Steps to Scalable Private Cloud Design

Building a scalable private cloud can save costs, improve security, and keep your business flexible. Here's a quick guide to designing one that grows with your needs while staying compliant with UK regulations:

1. Standardise Your Infrastructure: Simplify IT operations, reduce costs, and meet compliance requirements like UK GDPR by creating uniform hardware, software, and configurations.
2. Consolidate Resources and Use Virtualisation: Optimise resource usage and save up to 55% on power consumption by consolidating data centres and using virtualisation tools like VMware, Hyper-V, or KVM.
3. Implement Automation and Orchestration: Automate repetitive tasks and manage workflows with tools like Terraform and Kubernetes to reduce errors and boost efficiency.
4. Plan Resources and Growth: Forecast future needs, track cloud costs, and use horizontal scaling to handle demand without overspending.
5. Monitor Performance and Control Costs: Use real-time dashboards, audits, and tools like caching and load balancing to maintain performance and stay within budget.

Why it matters: Poor cloud design can lead to overspending (58% of organisations exceed cloud budgets) and data exposure (63% report incidents). Following these steps ensures your private cloud is cost-effective, secure, and scalable.

Step 1: Standardise Your Infrastructure

The first step in building a scalable private cloud is to standardise your infrastructure. This forms the foundation for growth, ensuring your systems are ready to handle increased demands effectively.

Why Standardisation Matters

Standardisation simplifies IT operations, reduces vendor costs, and consolidates purchasing power, leading to immediate savings and better efficiency. From an operational standpoint, having uniform systems makes IT management much smoother. When most of your equipment operates in the same way, maintenance becomes more straightforward, and your technical team can focus on mastering a single set of systems. This not only speeds up problem resolution but also ensures more reliable operations.

Standard IT infrastructure delivers scalability, repeatability, reliability, and cost optimisation as no network of disparate systems ever can. [1]

Another advantage is streamlined decision-making. Instead of evaluating countless solutions for every new challenge, your team can rely on established standards to address emerging needs [1].

To achieve standardisation, you can take these steps:

• Audit your infrastructure: Create an inventory of all tools and resources.
• Establish clear standards: Define hardware specifications, software versions, and configuration templates.
• Train your team: Ensure your staff is well-versed in the new standards.
• Monitor compliance: Regular checks help identify areas for improvement and ensure consistent adherence to the standards [2].

This approach not only boosts efficiency but also sets the stage for meeting the UK’s stringent compliance requirements.

UK Compliance Requirements

For UK businesses, standardising infrastructure isn’t just about operational gains - it’s also key to navigating complex regulatory demands. UK regulations, such as the UK GDPR, Data Protection Act 2018, Investigatory Powers Act 2016, and National Security and Investment Act 2021, place a strong emphasis on data sovereignty and protection [3].

When your systems follow the same protocols for security, data handling, and access control, implementing compliance measures becomes far more manageable. For example, tasks like maintaining records of data processing activities or conducting data protection impact assessments (DPIAs) under the UK GDPR are much simpler when your infrastructure is standardised [3].

The importance of data sovereignty is increasingly recognised. As Mark Boost, CEO of Civo, puts it:

The inability to ensure data remains within UK borders underscores the risks of depending on hyperscalers. If we keep outsourcing critical data infrastructure, we risk losing more than just technical control, we lose national independence. [4]

Jon Cosson, head of IT and chief information security officer at JM Finn, echoes this sentiment:

Data sovereignty is not a buzzword, it's survival. [4]

To support compliance efforts, consider deploying technologies like encryption, anonymisation, and secure storage. Additionally, develop a global data governance framework that outlines how data is collected, stored, and transferred. This should include policies on access, security, and retention [6].

The regulatory environment is constantly evolving. In 2022 alone, data protection authorities across Europe issued fines totalling approximately £1.44 billion - a 50% increase compared to the previous year [5]. A standardised infrastructure allows you to adapt to these changes without overhauling your systems entirely.

With datacentres classified as critical national infrastructure (CNI) by the UK government [4], maintaining high levels of security, reliability, and compliance is essential for scaling successfully in the UK market.

Step 2: Consolidate Resources and Use Virtualisation

Once your infrastructure is standardised, the next logical step is to consolidate resources and implement virtualisation. This approach not only optimises resource usage but also reduces costs and energy consumption. By building on a standardised foundation, you can make the most of your existing resources while preparing for scalable growth.

How to Consolidate Resources

Resource consolidation involves bringing together servers, storage, and networking components to cut down on inefficiencies and maximise performance. For example, consolidating data centres can result in cost reductions of up to 30%, a 35% boost in security, a 50% improvement in efficiency, and a 55% drop in power consumption [10].

A key part of this process is migrating virtual machines (VMs) and containerised applications. Interestingly, migrating containerised applications tends to be more energy-efficient and delivers better performance compared to traditional VM migration [8]. According to Gartner, 85% of infrastructure strategies will blend on-premises, colocation, cloud, and edge delivery options by 2025, a sharp rise from just 20% in 2020. This trend highlights the growing focus on achieving business outcomes rather than being tied to specific physical data centre locations [7].

Without the right hybrid migration strategy, you will miss opportunities to consolidate and optimize applications and services, losing out on savings and increasing risk. - Ensono [7]

This consolidation effort lays the groundwork for advanced virtualisation techniques.

Virtualisation Options

Virtualisation allows multiple virtual machines to run on a single physical server, separating workloads from hardware. This not only increases resource utilisation but also reduces the physical footprint, leading to significant savings on hardware, energy, and maintenance costs [9].

In the UK, three main virtualisation platforms are widely used: VMware vSphere, Microsoft Hyper-V, and KVM [13]. Each has its own strengths and pricing structure:

Note: Prices are approximate and based on current exchange rates. Licensing agreements may affect final costs.

VMware is often considered the industry leader, offering advanced features like live migration and fault tolerance. However, its licensing costs can be high - for instance, VMware vSphere Standard costs £1,014 per physical processor annually, with additional Windows Server licensing starting at £401 per year [11]. Microsoft Hyper-V, on the other hand, integrates seamlessly with Windows environments, with System Center licensing starting from £1,058 annually [11]. Meanwhile, KVM stands out as a cost-effective, open-source alternative, delivering enterprise-level performance without licensing fees - making it especially popular for cloud-based setups [12].

Selecting the right platform depends on your current infrastructure, budget, and technical capabilities. Many UK organisations find it effective to start with a single platform and expand gradually, which helps manage risks and control costs. Additionally, most virtualisation platforms offer centralised management tools that simplify administrative tasks and improve operational efficiency [13]. For those planning for future growth, it's worth noting that the global desktop virtualisation market is projected to reach £20.96 billion by 2030, signalling continued advancements in this area [14].

If you're unsure where to start, Hokstad Consulting can provide tailored advice on resource consolidation and virtualisation strategies to help you build a scalable, cost-efficient cloud infrastructure. With this foundation in place, the next step will focus on automation and orchestration to further streamline your operations.

Step 3: Implement Automation and Orchestration

Once your infrastructure is standardised and resources are consolidated, the next step is to introduce automation and orchestration. These tools help reduce manual tasks, streamline workflows, and enhance overall productivity, making operations more efficient [19][20].

The reliance on manual processes within cloud environments is still a concern. For instance, 38% of organisations using AWS reported deploying workloads or performing sensitive actions manually via the AWS console within a two-week period [16]. This reliance on manual intervention not only slows things down but also increases the risk of errors and limits scalability.

Automation vs Orchestration: What’s the Difference?

Before diving in, it’s important to understand the distinction between automation and orchestration, as they serve different purposes:

Infrastructure as Code (IaC)

Infrastructure as Code (IaC) has revolutionised how infrastructure is managed. Instead of manually configuring servers or networks, IaC uses machine-readable definition files to automate these tasks. This ensures consistency, reduces configuration drift, and improves compliance [17][20].

The growing popularity of IaC is evident, with the global market projected to hit USD 3,304.9 million by 2030, growing at a compound annual growth rate (CAGR) of 20.3% [17]. This reflects its increasing importance in modern IT management.

Some of the most widely used IaC tools include:

• Terraform: Ideal for multi-cloud environments, Terraform allows organisations to manage infrastructure across multiple providers. Its declarative approach lets you define the desired end state, and the system handles the rest [18].
• Ansible: Focused on automating repetitive IT tasks, Ansible is particularly effective for configuration management and application deployment [15].

For example, one e-commerce company reduced server deployment times from weeks to minutes using automation, while a financial institution cut compliance costs by 30% [19].

Container Orchestration

Managing containerised applications at scale is no small feat, and this is where container orchestration comes in. Tools like Kubernetes handle deployment, scaling, and management of these applications, ensuring everything runs smoothly [15].

Kubernetes has become the go-to solution for container orchestration. It offers features like flexible resource allocation, automatic scaling based on demand, and policy-based automation to maintain security and compliance. It also enables self-service provisioning, which helps eliminate bottlenecks in the development process [21][25].

Developers are overwhelmed by the amount of security configurations that are needed to secure the cloud…they no longer have to be security experts or worry about creating vulnerabilities for the organisation. - SVP Infrastructure & CISO, National Financial Company [18]

To get the most out of container orchestration, follow these best practices:

• Start with specific use cases.
• Engage stakeholders early in the process.
• Use monitoring tools to track performance.
• Standardise templates with version control.
• Validate workflows through automated testing [23][24].

Here’s how a typical orchestration workflow might look: a developer logs into a portal and inputs the required specifications for a compute environment. The system then verifies approvals, executes scripts to provision resources, and notifies all relevant parties once the process is complete [22]. This eliminates manual handoffs and significantly reduces deployment times.

Hokstad Consulting brings deep expertise in DevOps to design and implement robust automation and orchestration systems tailored to your scaling needs. Their experience in creating automated CI/CD pipelines ensures your operations remain efficient and scalable.

This methodical approach sets the stage for precise resource management and prepares your organisation for the growth opportunities ahead.

Step 4: Plan Resources and Growth

Once you've automated and organised your processes, the next step is to focus on planning resources and growth. This means assessing your current capacity, anticipating future demands, and setting up systems that can handle these changes without overspending.

Interestingly, only a third of organisations track costs accurately, while 58% exceed their cloud budgets [26]. Even more concerning, 90% of professionals report that poor visibility into cloud costs hampers their ability to perform effectively [26].

Start by reviewing past performance to better predict what lies ahead.

Forecasting and Audits

Capacity planning begins with studying historical usage patterns to guide future needs. Cloud forecasting involves examining past usage and factoring in upcoming projects to estimate costs [26]. It's not a one-time task but an ongoing process that requires regular updates.

Dive into historical usage data, including seasonal and cyclic trends, for precise forecasting [27]. For instance, an e-commerce platform must account for seasonal surges during peak shopping periods and weekly fluctuations. Using multiple forecasting approaches can provide a more rounded view of future expenses [26]. Some common methods include:

• Simple (Naïve) Forecasting: Assumes spending remains stable, ideal for consistent usage patterns.
• Trend-Based Forecasting: Projects based on past trends but may falter with sudden changes.
• Driver-Based Forecasting: Considers business factors like customer growth.
• Net New Workload Forecasting: Estimates costs for workloads that are yet to launch.

Regular audits are essential. Track metrics such as throughput, response time, availability, reliability, and scalability, while keeping an eye on detailed costs to ensure resources are being used effectively [26].

Scheduling monthly or quarterly reviews to compare forecasts with actual usage can help identify gaps and refine your models [29]. To avoid unexpected costs, set up budget alerts and anomaly detection in pounds sterling. For example, you could set alerts at 75% and 90% of a £10,000 monthly budget, giving you time to address issues before hitting your limit [26].

Horizontal Scaling

Once you’ve nailed down your forecasts, focus on aligning your scalability strategy. Horizontal scaling, which involves adding servers to balance workloads, helps prevent single points of failure [28].

To make the most of horizontal scaling, design applications to be modular and stateless, allowing workloads to distribute efficiently [28]. Auto-scaling policies are crucial - define clear metrics for scaling in and out, including thresholds and cooldown periods [28]. Load balancers also play a key role by evenly distributing traffic and ensuring only healthy servers handle requests.

Regular scalability testing is a must. It helps pinpoint bottlenecks and fine-tune scaling thresholds [28]. Real-time monitoring offers continuous insights into resource use, enabling proactive adjustments [29]. As Evangelos Kotsovinos, Executive Director for IT Strategy at Morgan Stanley, explains:

Capacity management is the most underestimated problem of cloud computing. One of the main reasons for using cloud computing services is to get efficiency and cost savings. And maximum IT efficiency on the cloud comes from good capacity planning and management. – Evangelos Kotsovinos [29]

To refine your scaling strategies, consider services like Hokstad Consulting, which specialise in cloud cost engineering. Their expertise has helped organisations cut cloud costs by 30–50% while maintaining performance, ensuring scaling strategies meet both technical and financial goals.

This structured approach to resource planning and growth sets the stage for implementing performance monitoring and cost control measures.

Step 5: Monitor Performance and Control Costs

The final step in creating a scalable private cloud involves setting up strong monitoring systems and effective cost management practices. These measures ensure your cloud remains efficient and financially sustainable, building on earlier steps like resource planning and automation to tie together performance tracking with budget control.

Continuous Monitoring

Keeping an eye on your private cloud in real time is essential. Centralised dashboards provide a clear view of operations, using key performance indicators (KPIs) and metrics to track resource usage and identify inefficiencies. They also support proactive incident management by triggering alerts for issues like performance drops, availability problems, or load imbalances [30][31][32]. Together with standardisation and resource consolidation, continuous monitoring creates a feedback loop that supports scalability.

Stuart Gray, Frontend Site Performance at Shop Direct, highlights the importance of monitoring:

With Akamai mPulse, we can pinpoint performance degradations and substantiate the value of performance improvements to optimise the customer experience and, in turn, our revenues. [31]

For instance, Melvin Rodriguez, COO of Mielle Organics, uses a customised NetSuite dashboard for daily monitoring, ensuring better operational visibility [32]. In the UK, cloud observability and performance monitoring services typically cost between £525 and £1,800 per unit per day [30].

Identifying Cost Savings

Regular audits of cloud expenses are key to spotting inefficiencies and reallocating resources effectively. These audits can reveal idle, underused, or orphaned resources, providing a detailed view of how services, instances, and departments consume resources. By tagging resources accurately and benchmarking against historical data, you can uncover cost anomalies and improve allocation [33].

Automating parts of the audit process can reduce manual effort while providing real-time insights. This helps guide decisions on architecture changes and resource adjustments, often referred to as rightsizing.

To optimise performance and control costs, consider combining caching, load balancing, and autoscaling. Caching reduces redundant operations and backend demand, while load balancing spreads workloads evenly across servers. When integrated with autoscaling, it ensures fluctuations in demand are handled efficiently. Monitoring metrics like cache hit ratios and latency helps keep these strategies aligned with cost goals, avoiding over-provisioning [34][35][36].

For expert guidance, Hokstad Consulting offers cloud cost engineering services. They’ve helped organisations cut cloud costs by 30–50% while maintaining high performance standards. Their approach blends technical fine-tuning with financial discipline, ensuring your cloud scaling efforts meet both operational and budgetary needs.

With robust monitoring and cost management in place, your private cloud becomes a well-oiled machine, balancing technical excellence with financial responsibility.

Conclusion

Creating a scalable private cloud calls for a well-thought-out approach that balances technical efficiency with smart financial planning. By focusing on standardisation, resource consolidation, automation, careful planning, and cost management, businesses can build an infrastructure primed for growth while staying ready to meet future challenges.

These strategies lay the groundwork for a robust and adaptable private cloud. Organisations that adopt them can significantly cut IT costs by making better use of resources and managing infrastructure more effectively. At the same time, private cloud solutions offer the scalability and control UK businesses need, leveraging existing on-premises setups to provide security and flexibility [37] [38].

Peter Hall, Head of IT Operations at Fortnox, highlights the importance of this approach:

We are often asked if we are running our own servers and where data is stored. We would not have the same sense of control if we went with the public cloud [37].
