Scenario
You work for a company that holds an annual capture the flag (CTF) competition. In the past, competitions had at least 1,500 people competing against one another. There are 250 challenges in the system ranging from general IT to cybersecurity. There is no way to know exactly how long it takes participants to perform a challenge; however, on average, some investigations have determined between 30 seconds to 1 minute. The system must stay up during the competition. It is estimated that each year the number of participants will grow 15%. It has been decided that in the upcoming year, the system will be delivered to contestants from the Cloud as Software as a Service (SaaS) instead of an on-premise system. The main reason for this is that a power outage occurred last year, and the system was not operational for 4 hours during the 72-hour event. Management does not want that to happen again.
You work in a small IT team, and your director of IT asked your team to research Amazon and Microsoft for the CTF system. Facebook developed the CTF system, is open source, and runs on Ubuntu. You will also determine the total cost of ownership (TCO) of the two providers.
Full Answer Section
- Cost-Effectiveness: The TCO of the solution should be reasonable.
Evaluating Amazon Web Services (AWS) and Microsoft Azure
Amazon Web Services (AWS):
-
Pros:
- Scalability: AWS offers a wide range of scalable services, including EC2, ECS, and Lambda.
- Reliability: AWS has a strong track record of reliability and offers services like Route 53 for DNS and CloudFront for content delivery.
- Security: AWS provides robust security features, including IAM, security groups, and network ACLs.
- Performance: AWS offers high-performance services like EC2 instances and databases.
-
Cons:
- Complexity: AWS can be complex to manage, especially for smaller teams.
- Cost: AWS can be expensive, especially if not managed carefully.
Microsoft Azure:
-
Pros:
- Integration with Microsoft Products: Azure integrates well with Microsoft products like Active Directory and Office 365.
- Ease of Use: Azure is often considered more user-friendly than AWS.
- Security: Azure offers strong security features, including Azure Security Center and Azure Active Directory.
-
Cons:
- Maturity: While Azure has matured significantly, it may still lag behind AWS in some areas, particularly in terms of global infrastructure and services.
Total Cost of Ownership (TCO) Considerations
When calculating the TCO, consider the following factors:
- Infrastructure Costs: Costs of virtual machines, storage, and networking.
- Licensing Costs: Costs of software licenses, if applicable.
- Personnel Costs: Costs of IT staff to manage the infrastructure and application.
- Operational Costs: Costs of monitoring, backup, and disaster recovery.
Both AWS and Azure offer detailed cost calculators to help estimate costs. However, the actual TCO will depend on various factors, including the specific services used, the number of users, and the level of support required.
Recommendations
Based on the requirements and the strengths and weaknesses of each provider, AWS appears to be a strong choice for the CTF SaaS system. It offers superior scalability, reliability, and performance, which are critical for a large-scale event. However, it's essential to carefully plan and manage the infrastructure to control costs.
To minimize costs and maximize efficiency, consider the following strategies:
- Utilize Serverless Technologies: AWS Lambda can be used to execute code in response to events, reducing infrastructure costs and improving scalability.
- Implement Automated Scaling: Use AWS Auto Scaling to automatically adjust the number of instances based on demand.
- Optimize Resource Utilization: Monitor resource usage and optimize configurations to reduce costs.
- Leverage Cost-Effective Storage Options: Use S3 for storing static assets and EBS for storing databases and other dynamic content.
By carefully considering these factors and leveraging the strengths of AWS, you can ensure a successful and cost-effective CTF SaaS solution.
