Mobile App Chapter 15: Problem 4
Suppose an architectural element will be used in a high-availability system. How might that affect its interface documentation? Suppose the same element will now be used in a high-security system. What might you document differently?
Short Answer
Expert verified
For high-availability, document redundancy, failover mechanisms, and uptime. For high-security, document encryption, access controls, and auditing.
Step by step solution
01
- Identify Requirements for High-Availability
Determine the requirements for a high-availability system. This typically involves ensuring that the system can continue to function even when part of it fails. The documentation should include details on redundancy, failover mechanisms, and uptime guarantees.
02
- Document Redundancy
Describe how redundancy is implemented. This includes outlining any backup systems, parallel processes, or other methods used to ensure that the system remains operational.
03
- Explain Failover Mechanisms
Detail the failover mechanisms in place. This might include specific procedures for switching to a secondary system when the primary system fails.
04
- Uptime and Maintenance
Include information on the expected uptime and how maintenance will be handled to minimize downtime. Specify any Service Level Agreements (SLAs) related to system availability.
05
- Identify Requirements for High-Security
Determine the requirements for a high-security system. This involves ensuring data confidentiality, integrity, and authentication. The documentation should cover encryption methods, access controls, and auditing.
06
- Document Encryption Methods
Explain the encryption methods used to protect data both at rest and in transit. Specify the encryption algorithms and key management practices.
07
- Access Controls
Describe the access control methods implemented. This could include user authentication protocols, role-based access controls (RBAC), and multi-factor authentication (MFA).
08
- Auditing and Monitoring
Detail the auditing and monitoring practices. Include information about how access logs are maintained and reviewed, intrusion detection systems, and regular security assessments.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
high-availability documentation
High-availability documentation is crucial for ensuring your system remains functional and reliable. It provides a detailed guide on key aspects like redundancy, failover mechanisms, and uptime guarantees. This documentation should outline how high-availability is achieved and maintained. It should be comprehensive and easily accessible to all stakeholders.
Make sure to include clear guidelines on:
Make sure to include clear guidelines on:
- Sustainability during failures
- Strategies for minimizing downtime
- Configuring backup systems effectively
failover mechanisms
Failover mechanisms are essential for maintaining continuity when parts of the system fail. They ensure a seamless transition from the primary to the secondary system.
To document failover mechanisms:
To document failover mechanisms:
- Describe the automatic processes that redirect traffic and workloads
- Specify manual procedures if automated failover isn't possible
- Include the conditions under which failover occurs
system redundancy
System redundancy involves having multiple components that can take over when the main system fails. Redundancy ensures that there’s no single point of failure.
Your documentation should cover:
Your documentation should cover:
- Backup systems and their locations
- Parallel processing units
- Data replication strategies
uptime guarantees
Uptime guarantees are commitments regarding the amount of time a system is expected to be operational. This is often agreed upon in Service Level Agreements (SLAs).
In your documentation, include:
In your documentation, include:
- The percentage uptime guaranteed (e.g., 99.99%)
- Maintenance schedules and windows
- Penalties or compensations for not meeting uptime guarantees
high-security requirements
For high-security systems, requirements focus on protecting data confidentiality, integrity, and authentication. These ensure that unauthorized users cannot access or alter the data.
Document these aspects:
Document these aspects:
- Strong encryption methods
- Robust access control mechanisms
- Regular security audits
encryption methods
Encryption methods are vital for protecting data at rest and in transit. They convert data into a code to prevent unauthorized access.
Include details on:
Include details on:
- Encryption algorithms used (e.g., AES, RSA)
- Key management practices
- Encryption application protocols
access control
Access control methods protect your system by verifying the identities of users and determining their permissions.
Different methods include:
Different methods include:
- User authentication (passwords, biometrics)
- Role-Based Access Control (RBAC)
- Multi-Factor Authentication (MFA)
security auditing
Security auditing is the practice of reviewing and assessing the security measures in place. Regular audits help to identify vulnerabilities and ensure compliance with security standards.
Document:
Document:
- How access logs are maintained and reviewed
- Intrusion detection and prevention systems
- Frequency and scope of regular security assessments
