1. Data Protection Server
The Data Protection Server plays a critical role in BCDR strategies. Using DPM, administrators can perform:
- Application-aware backups for Exchange, SQL, and SharePoint.
- File, folder, volume, and system state backups.
- VM protection for Hyper-V environments (Windows and Linux).
This ensures data integrity and streamlined recovery processes.
2. Web Services in Windows Server 2025
Web services enable interoperability between applications using XML-based protocols. Two main types:
- RESTful: Uses HTTP methods (GET, POST, PUT, DELETE) and URIs for scalable interactions.
- SOAP: Uses structured XML messages with built-in error handling and security.
3. IIS in Windows Server 2025
IIS 10 is Microsoft’s web server platform supporting HTTP, HTTPS, FTP, FTPS, SMTP, and NNTP. New features include:
- Support for HTTP/2 and HTTP/3.
- PowerShell-based IIS administration.
- Wildcard host headers and HSTS management.
- Deployment on Nano Server and containers.
4. FTP
FTP transfers files using a client/server model. Port 21 manages control connections, while port 20 handles data transfer. Adding the FTP Server role service in IIS enables secure file management.
5. Worker Processes
Each IIS application pool has a dedicated worker process to execute web applications. Isolation ensures stability and prevents issues in one pool from affecting others.
6. Ports Overview
- Well-Known Ports: 80 (HTTP), 443 (HTTPS), 21 (FTP), 25 (SMTP).
- Registered Ports: 3306 (MySQL), 5432 (PostgreSQL).
- Dynamic Ports: 49152–65535 for temporary connections.
7. SSL/TLS and Certificates
SSL/TLS encrypts communication between browsers and servers. Certificates issued by CAs authenticate websites and establish secure channels. TLS improves upon SSL with stronger encryption and validation methods.
Conclusion
Combining DPM for data protection with web technologies like IIS, FTP, and SSL/TLS creates a secure and resilient infrastructure in Windows Server 2025. These components ensure business continuity, secure communication, and efficient service hosting.
