CLCS 615 is a 3-credit graduate course at the University of Maryland Global Campus and one of the required core courses in the MS in Cloud Computing Systems.
UMGC describes it as a comprehensive exploration of cloud computing concepts, platforms and technologies, covering the principles, benefits and challenges of cloud-based solutions. Key technologies include cloud storage, networking, security and databases, and hands-on work with popular cloud platforms connects theory to real-world practice.
Where CLCS 605 introduces the cloud, CLCS 615 goes deeper into the building blocks. The challenge is choosing between many similar-looking services and justifying the choice. UMGC notes that students may receive credit for only one of CLCS 615 or CCS 610.

What CLCS 615 Covers
- Principles, benefits and challenges: elasticity, resilience and cost on one side; complexity, lock-in and skills gaps on the other.
- Cloud storage: object, block and file storage, and storage tiers.
- Cloud networking: virtual networks, subnets, gateways and connectivity.
- Cloud security: identity and access management, encryption and monitoring.
- Cloud databases: managed relational and non-relational (NoSQL) databases.
- Popular platforms: hands-on experience applying these services.
Key Concepts Explained
Three Kinds of Storage
| Type | Best for |
|---|---|
| Object storage | Large amounts of unstructured data: backups, images, logs |
| Block storage | Disks attached to virtual machines, databases needing fast access |
| File storage | Shared folders accessed by several servers at once |
Example: A photo-sharing app stores user uploads in object storage, runs its database on block storage attached to a server (or a managed database), and uses file storage for a shared configuration folder. Older photos rarely viewed move to a cheaper archive tier after 90 days through a lifecycle rule.
Relational Versus NoSQL
Relational databases suit structured data with relationships and transactions, such as orders and payments. NoSQL databases suit flexible or very high-volume data, such as session data or product catalogs with varying attributes. Managed versions of both shift patching and backups to the provider.
Identity and Access Management
Access in the cloud is controlled through identities, roles and policies. The principle of least privilege gives each user or service only the permissions it needs.
Example: A reporting application needs to read files from one storage bucket. Rather than giving it administrator rights, an administrator creates a role that allows read-only access to that bucket alone. If the application is compromised, the damage is limited.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Platform exercise | Practical configuration | Document each step and explain why the setting was chosen |
| Service selection paper | Matching services to needs | List requirements, compare options, justify the choice |
| Benefits and challenges analysis | Balanced judgment | Weigh each benefit against a realistic risk for the scenario |
| Security configuration review | Applying security principles | Check access, encryption and logging against best practice |
A Method for Service Selection Papers
Many CLCS 615 tasks ask you to recommend services for a scenario. A repeatable method keeps the answer focused and easy to mark:
- Extract requirements: data type and volume, access pattern, performance, availability, security and budget.
- Shortlist options: two or three services that could meet them, across one or more providers.
- Compare: a table scoring each option against the requirements, with brief notes.
- Recommend: the best fit, with the trade-offs you accept.
- Secure and operate: the access, encryption, backup and monitoring settings you would apply.
Ending with operational settings shows that you understand a service choice is only the start; how it is configured decides whether it is reliable and secure.
Where Students Get Stuck
- Too many similar services. Start from requirements (data type, access pattern, budget) and eliminate options.
- Over-permissive access. Lab shortcuts like full administrator rights are poor practice in written answers.
- Ignoring data transfer costs. Moving data out of a cloud or between regions often costs money.
- Benefits without challenges. Graduate answers should weigh both.
Study Tips for CLCS 615
- Keep a decision table for storage and database choices with "use when" and "avoid when" columns.
- Use free tiers and sandbox labs carefully and clean up resources after each exercise.
- Read provider documentation for the services in your labs; it is the most accurate source.
