content: str = """
Cloud providers offer various storage classes optimized for different 
access patterns, performance requirements, and costs. Effective lifecycle 
management ensures data is stored in the most cost-effective tier.

**Common Storage Classes (Object Storage):**
1. **Standard / Hot:** High durability and availability for frequently 
   accessed data. Highest storage cost but lowest access cost.
2. **Infrequent Access (IA) / Cool:** Lower storage cost but higher 
   access cost. Ideal for data that is not accessed often but needs to be 
   available immediately when requested.
3. **Archive / Cold (e.g., Glacier):** Lowest storage cost for long-term 
   retention. Retrieval can take minutes to hours. Ideal for backups and 
   compliance data.

**Lifecycle Policies:**
Automated rules that transition objects between storage classes or delete 
them after a certain period. For example, a policy might move logs to 
Infrequent Access after 30 days and delete them after 365 days.

**Block vs. File vs. Object Storage:**
*   **Block Storage (EBS, Managed Disks):** High-performance storage 
    attached to instances. Best for databases and OS volumes.
*   **File Storage (EFS, Azure Files):** Shared file systems accessible by 
    multiple instances simultaneously.
*   **Object Storage (S3, Blob Storage):** Highly scalable storage for 
    unstructured data, accessed via APIs.

Architects must align storage choices with data retention policies and 
access frequency to optimize both performance and spend.
