To Cloud or not To Cloud
¿Es la nube la solución adecuada para tu empresa?

Context
Cloud
IaaS
PPU
API
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
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
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
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
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)
It’s all about money
 Leverage Economies of Scale
 Rule of thumb
Cloud Bandwidth «Expensive»
Cloud Storage «Expensive»
Cloud Processing Cheap
Elasticity Priceless
Summary
Low needs Hosting, SaaS
High & core
needs
Dedicated
Elasticity Cloud (IaaS)

CloudCamp BCN, To Cloud or not to Cloud

  • 1. To Cloud or not To Cloud ¿Es la nube la solución adecuada para tu empresa? Sergi Morales, CISM Founder & CTO
  • 2.
  • 4. 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
  • 5. 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
  • 6. 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
  • 7. 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
  • 8. 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)
  • 9. It’s all about money  Leverage Economies of Scale  Rule of thumb Cloud Bandwidth «Expensive» Cloud Storage «Expensive» Cloud Processing Cheap Elasticity Priceless
  • 10. Summary Low needs Hosting, SaaS High & core needs Dedicated Elasticity Cloud (IaaS)
