Newest published work from this author, with reader-loved stories beside it.
Follow one legitimate request through gates, reception, inspection, quotas, and locked floors to understand firewalls, proxies, WAFs, API gateways, DDoS defence, segmentation, and Zero Trust.
2018
Follow one payroll document from storage to delivery and learn data at rest, encryption, hashing, HMAC, signatures, TLS 1.3, certificates, PKI, mTLS, KMS, and envelope encryption.
008
One leaked CI key exposes the full chain: cloud responsibility, IAM, secrets, container supply chain, Kubernetes, serverless, service identity, mTLS, API authorization, OWASP, and useful evidence.
0010
An employee can prove who they are and still be forbidden from issuing a refund. Use that incident to master passwords, MFA, sessions, JWT, OAuth, OIDC, RBAC, ABAC, and least privilege.
2014
A house before a holiday, one private office file, and one upload flow make assets, threats, CIA, STRIDE, threat modelling, and defence in depth finally connect.

Riya only knows SnackNow feels slow. Aman turns that complaint into latency, throughput, percentiles, SLOs, testing, monitoring, and a bottleneck he can actually fix.
105
SnackNow moves from storing orders to understanding millions of orders, clicks, logs, and events. Learn Big Data, the Vs, data lakes, Delta Lake, batch, stream, and terabytes-per-day pipelines.
205
SnackNow's analytics files outgrow one server disk. Learn file systems, HDFS, NameNode, DataNodes, blocks, replication, rebalancing, latency, throughput, CephFS, and GlusterFS.
105
SnackNow should not put food photos, videos, invoices, and backups directly into database rows. Learn object storage, buckets, keys, metadata, presigned URLs, lifecycle, cost, and security.
004
SnackNow's app servers are fine, but the database is sweating. Learn vertical scaling, read replicas, replication lag, sharding, consistent hashing, and polyglot persistence.

At 6:58 PM SnackNow loses an entire cloud region. Build a practical DR plan with RTO, RPO, pilot light, warm standby, multi-region failover, quorum, drills, and safe failback.
209
A mistaken command deletes hundreds of SnackNow orders and replication copies the damage. Learn how backups, PITR, RPO, RTO, retention, immutability, and restore testing recover the business.

One SnackNow server fails at 7:07 PM and takes the business with it. Rebuild the incident with redundancy, N+1 capacity, health checks, failover, graceful degradation, and safe failback.
104
At 7:07 PM SnackNow stays online, yet one successful payment produces the wrong result. That incident reveals what reliability really asks an application to promise.

SnackNow's order history collapses during the dinner rush. Aman follows the evidence from slow-query logs and EXPLAIN plans to indexes, N+1 fixes, pooling, pagination, and safer read models.
004
SnackNow receives many orders at once. One cook can juggle them, several cooks can truly work together, and one shared order slip can still ruin the evening.
104
Riya waits while SnackNow sends emails, updates analytics, and calls every service in line. Aman uses an order-slip queue to separate urgent work from work that can finish safely in the background.
204
SnackNow keeps asking its database for the same menu. Aman builds a ready-chai counter to explain cache hits, misses, TTL, invalidation, eviction, and stampede protection.
