Wow how cool

1. Multi-Tenancy & Availability Shreeman M (RA2211028010166)

2. What is Multi-Tenancy? One Software Instance Single application serves multiple customers (tenants) simultaneously Logical Isolation Each tenant's data stays separate and secure, like individual Netflix profiles Shared Resources Everyone uses the same underlying infrastructure efficiently An analogy: Netflix profiles on one account – shared platform, personalized experience, separate viewing histories.

3. Types of Multi-Tenancy Architecture Database Multi-Tenancy Shared database with tenant-specific tables. Like having labeled shelves in a shared fridge. Schema-Based Separate schemas in shared database. Think mini-fridges in a shared kitchen. Dedicated Instance Complete isolation per tenant. Like having your own personal kitchen – secure but expensive. Storage Multi-Tenancy Shared storage with access controls. Like library shelves with borrower cards.

4. Benefits of Multi-Tenancy 💰 Cost Efficiency Shared infrastructure means lower costs per tenant – like splitting the gym membership among friends 🚀 Easy Updates Update once, everyone benefits instantly – no visiting each apartment to fix the elevator 📈 Infinite Scalability Add new tenants without rebuilding infrastructure – more gym members, same equipment

5. What is High Availability? Always Accessible & Reliable Systems that stay running 24/7, even when things go wrong. Like a 24-hour convenience store that never closes. Key Metrics Uptime percentage: 99.9% = 8.76 hours down/year SLA commitments: Guaranteed service levels Fault tolerance: Keep running despite failures

6. Achieving High Availability 01 Load Balancing Distribute traffic across multiple servers – like having multiple checkout lanes at a busy store 02 Replication & Failover Backup systems ready to take over instantly – like standby generators in hospitals 03 Geographic Redundancy AWS/Azure availability zones across different locations – multiple hospital branches

7. Multi-Tenancy + Availability = Magic Failover Systems Redundant Servers Load Balancers Tenants When combined, you get efficient systems that never sleep . SaaS applications like Slack, Zoom, and Salesforce exemplify this perfect marriage.

8. Challenges & Trade-offs 🔒 Security Risks Data isolation between tenants – like ensuring apartment mail doesn't get mixed up ⚡ Resource Contention One tenant's heavy usage affects others – the noisy neighbor problem 💸 Cost vs Isolation Balancing shared efficiency with tenant-specific needs 🎯 Uptime Complexity Ensuring availability while serving diverse tenant requirements

9. The Perfect Flight Analogy Multi-Tenancy = Efficiency Many passengers sharing one aircraft Availability = Reliability Flights departing and arriving on schedule, always Together = Cloud Success The airline industry perfected this model – maximum efficiency with unwavering reliability . That's exactly what modern cloud development achieves.
