Scalability means that the cloud provider can maintain performance while experiencing changes in the size or volume of workloads. Ensure the cloud provider can scale up or down resources to meet your needs easily and without significant disruptions or cost spikes. Cloud providers scale resources in the following ways:
- Vertical scaling. The capacity of individual resources, such as processing power, memory, or storage, is upgraded or downgraded to accommodate fluctuating traffic or resource-intensive tasks.
- Horizontal scaling. Also called “scaling out”, this involves adding more instances or resources for efficient workload distribution.
- Global scaling. Businesses with a global presence need a cloud provider that can scale resources across data centers in different geographic regions.
Assess the track record of the provider to determine whether services are reliable and high-performance. Here are some of the performance factors to consider:
- Uptime and availability. Check the SLA (service level agreement) to determine the guaranteed percentage of time services are available.
- Response times. Make sure that the provider ensures that your applications are available with minimal latency.
- Network performance. Assess the provider’s network infrastructure as data transfer and communication between applications and users depends on the speed and reliability of the network.

4. Data Center Locations
The location of the cloud provider’s data centers is a critical consideration, as this can have an impact on the performance, compliance, and resilience of your services and applications. Smaller distances between your users and the data center decrease latency and improve response times. Furthermore, global businesses must contend with regional regulations, such as GDPR in Europe, which mandates that data is stored in data centers within a certain jurisdiction. Another benefit of geographically dispersed data centers is that disaster recovery and business continuity is greatly enhanced as data can be replicated across multiple data centers.
Robust security is a paramount factor when selecting a cloud provider, as it ensures your data, applications, and infrastructure are protected from threats and vulnerabilities. Here are some of the security concerns to consider:
- Physical security. Your cloud provider facilities should be protected with stringent physical access controls, including security personnel, surveillance cameras, biometric authentication, and other measures.
- Data encryption. Ensure that your cloud provider follows standard encryption practices and protects your data both at rest and in transit.
- Identity and access management (IAM). Robust IAM solutions, such as multi-factor authentication, role-based access controls, and least-privilege access, implemented by the cloud provider allow you to maintain strict control over who can access your resources.
- Security monitoring. Cloud providers offer cloud security monitoring tools that help you detect and respond to security incidents in real time.
- DDoS protection. Many cloud providers offer protection from distributed denial of service (DDoS) attacks by filtering malicious traffic and absorbing sudden traffic spikes.
- Data privacy. Cloud providers offer features and tools that align with privacy regulation, including anonymization and data masking, and the ability to restrict data processing according to user preferences.
While it is essential to carefully assess the security capabilities of the cloud provider, organizations need to understand that cloud security is based on the shared responsibility model and that they must also perform due diligence to ensure the safety and integrity of their data and applications.
For organizations operating in highly regulated industries or that handle sensitive data, compliance is a critical factor when choosing a cloud provider. Here are some of the compliance criteria to take into account:
- Industry-specific regulations. Organizations must find a cloud provider that offers solutions tailored to their specific industry, e.g., HIPAA for healthcare and PCI DSS for finance.
- Regional regulations. Organizations operating in certain regions must comply with local or regional regulations, such as GDPR in Europe.
- Security and compliance certifications. Establish whether the cloud provider has undergone specific security audits and assessments and obtained the relevant certifications, such as SOC2, ISO 27001, FedRAMP, and others.
- Auditing and monitoring tools. Find out whether the cloud provider offers tools that help you track and document compliance-related activities by creating logs, reports, and alerts.
7. Data Backup and Disaster Recovery
Business continuity depends on your ability to withstand and recover from disasters, whether they come in the form of natural events or malicious activity. When choosing a provider, thoroughly evaluate their data backup and disaster recovery capabilities to ensure the safety and availability of your data and applications. Here are some factors to consider:
- Data backup options. Providers typically offer different data backup options, including full, differential, and incremental backups, so it is necessary to assess the methods available and determine how they meet your data protection needs.
- Data retention policies. Find out how long backed-up data is retained as this information is crucial for compliance and your ability to recover data.
- Data security. Check that the cloud provider adequately protects your backed-up data with encryption and access controls to prevent unauthorized access and data breaches.
- Automation. Automated backup and recovery simplify the process of creating and restoring backups and also reduce the risk of human error.
- RTO and RPO. Examine the recovery time objective (RTO) and recovery point objective (RPO) that the cloud provider offers. These metrics determine the time it takes to recover from an adverse event and the acceptable data loss, respectively.
- Data redundancy. Check that the cloud provider offers built-in redundancy features across different geographical locations to enhance the safety and availability of your data and services.
8. Cost and Pricing Structure
The cost of cloud services directly impacts the financial feasibility of an organization’s cloud adoption. Cloud providers typically offer different pricing models for their services and also provide detailed cost breakdowns for various available resources. Here are some essential considerations regarding cloud costs:
- Pricing model. These are often divided into three types. The pay-as-you-go model charges you based on the actual resources you use. The subscription-based model provides fixed costs for monthly or yearly commitments. If your workloads have predictable resource demands, you can benefit from reserved instances, which come with cost savings on long-term commitments.
- Resource costs. Various cloud resources come with different prices and cloud providers offer different resources and storage, each with its own pricing structure. Choose the instance types and storage classes that match your use and budget.
- Data transfer costs. Check data transfer costs, which include fees for data ingress and egress. Consider how the volume of data transfer will impact your overall cloud costs.
