Selecting the Right Cloud Provider: Key Considerations for Moving to the Cloud

1. Cost Analysis

Research indicates that around 28% to 30% of cloud spending goes to waste due to unnecessary resources. This highlights the importance of conducting a thorough cost analysis to ensure efficiency.

Direct Platform Costs

Cloud services come with a range of expenses, and understanding these is crucial for effective budgeting:

• Base rates: Either subscription-based or pay-as-you-go pricing models.
• Data transfer fees: Particularly steep for cross-region transfers.
• Storage costs: Vary depending on the tier and how frequently data is accessed.
• Support plans: Fees differ based on the level of support you choose.

"The main barrier to adopting cloud computing is the unknown cost." - Pilotcore

One common challenge is hidden fees. These include charges for data transfers, retrieving stored data, and fluctuating support costs, all of which can significantly drive up the overall expense.

Cost Optimisation Strategies

With the right strategies, businesses can cut cloud programme costs by 15–25% without compromising performance. Here’s how:

• Resource Management: Automate the process of rightsizing resources during provisioning. Remove unused items like idle clusters and redundant snapshots promptly.
• Strategic Purchasing: For workloads with predictable patterns, using reserved instances or savings plans can lead to substantial discounts.
• Monitoring and Control: Leverage cost management tools to monitor your spending and set up budget alerts to avoid unexpected expenses.

Interestingly, 82% of SMBs report lower costs after moving to the cloud, and 70% of them reinvest these savings into innovation. To maximise these benefits, consider working with specialists to implement FinOps practices. These methods align your spending with business goals. Providers like Critical Cloud (https://criticalcloud.ai) offer tailored expertise to help you maintain cost-efficient cloud operations.

2. Growth Capacity

When it comes to long-term success, a platform's ability to grow alongside your needs is crucial. Interestingly, 51% of organisations identify cost as the biggest hurdle to scaling effectively. This makes it essential to choose a platform that strikes the right balance between scalability and affordability. Let’s dive into how different scaling approaches can support your growth goals.

Types of Scaling Capabilities

Modern cloud platforms provide various methods to handle increasing workloads. Here's a quick overview:

Auto-scaling and Load Management

Today’s advanced load balancers can handle over 1 million queries per second. This is where auto-scaling becomes a game-changer.

"Auto scaling is all about adjusting the number of running instances based on the current demand. Think of it as having a thermostat for your servers that automatically turns on more capacity when your application heats up and reduces capacity when things cool down." - Steven Moore, FinOps Specialist

For example, e-commerce platforms often rely on auto-scaling during events like Black Friday, where traffic surges temporarily. This ensures they can handle the load without overcommitting resources during quieter periods.

Hidden Growth Constraints

Strategic scaling can reduce operational problems by 40% compared to reactive methods. However, not all platforms are created equal. Keep an eye on these potential constraints:

• Resource Limits: Are there caps on the number of instances or data processing capabilities?
• Geographic Distribution: Does the platform support deployments across multiple regions?
• Cost Progression: How do costs increase as your usage grows?
• Technical Dependencies: Is the platform compatible with your current tools and systems?

Regular scalability tests and pre-defined usage thresholds can help trigger automatic scaling actions, ensuring your platform maintains performance while keeping costs under control.

For businesses navigating these complexities, working with cloud operations experts can make a big difference. Companies like Critical Cloud, for instance, specialise in helping digital agencies and SaaS providers implement efficient scaling strategies that preserve performance without adding unnecessary expenses.

3. Data Protection Standards

Protecting data isn't just about keeping your information safe - it's about staying compliant and ensuring your business can operate without interruptions. With GDPR fines reaching up to 4% of global turnover or more than £17 million, security is just as important as cost and scalability when choosing the right platform.

Regulatory Requirements

The Digital Operational Resilience Act (DORA), enforceable from 17 January 2025, adds new layers of compliance for businesses. Cloud platforms now need to meet specific standards, including:

These rules highlight the essential security elements to prioritise in your cloud platform.

Essential Security Features

To meet these standards, your platform should include:

• Encryption Standards: Ensure TLS 1.2 or higher for in-transit data and AES-256 encryption for stored data.
• Access Controls: Use role-based access, multi-factor authentication, and audit logging to regulate and track access.
• Compliance Framework Support: The platform should align with frameworks like the NIS 2 Directive, CRA, and PSTI Act.

Implementation Considerations

Bringing in cloud operations specialists can simplify compliance. Providers like Critical Cloud offer infrastructure pre-aligned with ISO 27001 and other industry standards, allowing digital agencies and SaaS companies to uphold high security levels without an internal security team.

"The European data protection board (EDPB), responsible for European data protection laws, emphasises the use of encryption and pseudonymisation as the means of appropriate technical and organisational measures."

To stay ahead, establish regular security assessments, clear incident response protocols, documented procedures, and continuous monitoring.

Up next, we'll explore how these standards tie into operational resilience.

4. Uptime and Speed

When choosing a cloud platform, reliability and performance are two factors you simply can't overlook. Uptime guarantees and response times directly impact your operations, so understanding these metrics is key to making an informed decision.
