Azure vs AWS vs Google Cloud - Costs and currency aspects
Choosing a cloud provider requires not only technical considerations, but also an analysis of operating costs. The expenses of Azure, AWS, and Google Cloud vary and depend on numerous factors, such as the selected service, the duration of use, the amount of data and the geographical region. Currency fluctuations and geographical factors can also influence the overall costs. This chapter attempts to take a closer look at the cost aspects and discusses ways to monitor and optimize costs in the cloud.
Cost structures and pricing models in general
Azure, AWS, and Google Cloud use similar pricing models based on the pay-as-you-go principle, where customers only pay for the resources they actually use. However, the providers differ in their specific pricing for services such as compute instances, storage options and network services. All three providers also offer long-term reservations or commitments, which can lead to significant cost savings.
Consideration of currency fluctuations and geographical factors
- Costs can also be affected by currency fluctuations, especially for companies outside the US. Providers bill their services in different currencies, and currency fluctuations can unexpectedly increase or decrease cloud costs.
- Geographical factors also play a role. Prices for cloud services can vary by region, with factors such as local taxes, availability of energy resources and proximity to data centers to consider.
Cost comparison between Azure, AWS, and GCP
A direct cost comparison is complex as it depends on the specific requirements of the solution and cannot be presented in a generalized way. In general, AWS offers a very wide range of services, which can lead to a more complex pricing structure. Azure is particularly attractive for companies that have already invested in the Microsoft ecosystem. Google Cloud often offers attractive pricing for data processing and storage, especially for long-term use.
Additional articles will follow showing specific comparisons of very popular services. These will attempt to take a closer look at the cost and feature structure. Just sign up for the newsletter so you don’t miss any of it.
Ongoing cost monitoring and optimization
Budget alerts and reports: All three providers offer spend monitoring tools that can be used to set up budget alerts to avoid cost overruns.
Cost management tools: Tools such as AWS Cost Explorer, Azure Cost Management + Billing and Google Cloud’s Cost Management provide detailed insights into usage and enable more accurate budget planning and cost optimization.
Automated scaling: The use of automated scaling can contribute to cost optimization by automatically adjusting resources to actual demand.
Reservations and discounts for long-term usage: Committing to longer-term usage can lead to significant savings. Companies should consider these options and use them where it makes sense.
Cost analysis and ongoing monitoring are essential to optimize cloud costs and avoid surprises in the bill. Using the tools and resources available, companies can manage, analyze and optimize their cloud expenses. The problem with this topic is that the SaaS solution must already be in operation in order to use these tools. If the architecture or the implementation of the functions is not well thought out, then all the on-board tools are of no use and the costs rise and rise with the number of users.
This is where we come into play!
In addition to automated infrastructure as code, this is an important area that we have dedicated ourselves to, namely the estimation of operating costs even before any code has been developed. All three providers have tools in their portfolio that are designed to help estimate costs. However, it is not possible to map dynamic relationships, nor are the necessary data such as computing time, memory consumption or the complexity of database queries known. Only static comparisons with fictitious configurations can be created.

However, to realize the full potential of your cloud solution, it is not only important to take a quick look at the SLAs, but also how the solution has been configured and designed overall. It is extremely important that you are clear about the availability guarantees you want to achieve before you begin development activities. Here are some of the key considerations.
Key considerations for PaaS optimization
Multi-regional and multi-zonal distribution
- Geographical redundancy: Distribute your applications and data across multiple geographical regions and availability zones within a cloud provider. This protects against outages that could affect an entire region or zone.
Automatic scaling and load balancing
- Scalability: Implement automatic scaling to dynamically adjust the number of instances to the current load. This prevents individual resources from being overloaded and helps to maintain availability.
- Load balancing: Use load balancers to distribute requests evenly across all available instances. This not only improves performance, but also increases reliability as individual points of failure are avoided.
Failover strategies and recovery plans
- Automatic failover: Set up automatic failover mechanisms to ensure a seamless transition to replacement resources or services in the event of outages.
- Disaster Recovery (DR): Develop a comprehensive DR plan that is tested regularly. This should provide for the recovery of data and applications in other regions or zones to minimize business disruption.
Data replication and backups
- Data replication: Replicate important data across multiple locations. Many cloud services offer integrated replication functions that ensure data consistency and availability.
- Regular backups: Carry out regular backups and store them in geographically separate locations. Ensure that the backup and restore procedures are well documented and tested.
Network configuration and security
- Redundant network connections: Provide redundant network paths to reduce reliance on a single connection.
- Security measures: Implement comprehensive security measures such as network segmentation, encryption, privileged access management and regular security audits to protect systems from attacks that could lead to downtime.
Monitoring and alerting
- System monitoring: Use tools to monitor the performance and status of your cloud resources in real time. This allows you to detect potential problems at an early stage and respond quickly.
- Alerts: Set up alerts that automatically send notifications when certain events or performance issues occur. This allows you to respond quickly to incidents and minimize the impact. Set up a computer emergency team.
Conclusion
By following these best practices when configuring cloud resources, organizations can ensure a high level of resilience for their cloud-based systems. This requires continuous evaluation and adaptation of strategies to changing requirements and threats. The bottom line is that a poor system design and concept can only be marginally compensated for by excellent SLAs and customer support from the PaaS provider.
