CloudCamp BCN, To Cloud or not to Cloud

  1. 1. To Cloud or not To Cloud ¿Es la nube la solución adecuada para tu empresa? Sergi Morales, CISM Founder & CTO
  2. 2. Context Cloud IaaS PPU API
  3. 3. Cloud is Good  Elasticity, scale-out  Commodity Infrastructure  x86, «small» machines  «low» performance per machine  No «security» concerns  Security is a state of mind  Technical proficiency
  4. 4. Cloud is Bad  Constant or very low/high needs  Specialized infrastructure  Sparc, PowerPC, GPUs  Huge amounts of RAM  Low latency network (Infiniband, 10 GbE,…)  Regulatory guidelines (LOPD, SOX, etc..)  Solution-in-a-Box
  5. 5. Hills (not peaks)  Wordpress with 180.000 followers  Crashing at every Tweet  1 GB Ram, ½ core, 32 GB HD, 400 GB BW  A “bit” of tuning:  Nginx vs. Apache  FastCGI PHP vs. mod_php  Caching 30s HTML
  6. 6. Elasticity  Show info to users when primary is down  Send a 503 so is not indexed by Google  Impossible to do Capacity Planning  1 instance during valleys  Auto configuring instances  Load Balancing + Auto-scaling  Replicating data, snapshots, multi-DC
  7. 7. Disaster Recovery  Code + assets on Object or Persistent Storage  DB transaction logs to Object Storage  Every X days consolidate logs  Every Y days test DR  Beware of SPOF (DNS, VPN, IPs on FW)
  8. 8. It’s all about money  Leverage Economies of Scale  Rule of thumb Cloud Bandwidth «Expensive» Cloud Storage «Expensive» Cloud Processing Cheap Elasticity Priceless
  9. 9. Summary Low needs Hosting, SaaS High & core needs Dedicated Elasticity Cloud (IaaS)
