Advanced Cloud Computing 2013 Notes. Yesterday I attended ACC2013 held @ Nimhans. Every conference provides a lot of inspiration and motivation to try out new things.
Session #1 - Inauguration Talk
Inauguration was done by Padma Bushan Rajaram. He explained cloud computing in very simple terms. Cloud computing is utility computing in simple terms. It was coined by a management professor named Chellapa.
He had earlier written a paper in 2005 on challenges in utility computing. He recollected his experiences with new jargon's/ technical abbreviations. He provided several examples on BYOD keyword. BYOD - Bring Your Own Drinks, BYOD - Bring Your Own Dope, BYOD - Bring Your Own Device (Recent usage). Storage and processing costs have come down. This has become a business potential for Amazon and Google to leverage it by outsourcing their excess storage and processing infrastructure.
He stressed on several areas to standardize the cloud for leverage the complete potential of it. Example- SLA to provide the required performance while hosting / sharing the infrastructure, Developing a universally usable cloud, interoperability between cloud providers
Session #2 - This was Talk by Karanataka's IT secretary VidyaShankar.IAS
He mentioned on developing trends Virtualization, Cloud and 3D Technologies. He mentioned
couple of products cloudmagic, cubby.
Session #3 - Connected Systems, Cloud beginner tech talk by Vikas Agarwal (Tally)
This talk pretty much focused on evolution of cloud computing. He tracked from the very beginning PC Era to cloud computing.
- Stage 1 - Mainframe Systems
- Stage 2 - PC Era (Moving data to personal systems)
- Stage 3 - LAN (Locally connected systems) - Intranets
- Stage 4 - Connected Era, WANs
- Stage 4 - Evolution of Internet (Globally Connected)
- Stage 5 - Cloud (Shared computing, storage) - Access anytime / anywhere
- Pooling Optimization
- Elasticity
- Efficiency
This talk focused on basics of cloud computing, challenges and applications in Fire and Security Domain. Key notes covered were
- Fallacies in Distributed computing
- Current Challenges in Fire & Security Domain are
- Identifying False Positives
- Predictive Analytics to identify and isolate false positives
- Real time monitoring
Yahoo has its own private cloud, Author provided details on Yahoo infrastructure and their software stack
Challenges
- Scaling systems as per growing data
- Data Partitioning
- Data Consistency
- Hardware provisioning
Benefits of Private Cloud
- Developers can focus on Application logic instead of designing for crash / recovery scenarios
- Focus on appealing content for users (UX Exp)
Requirements for Cloud
Multitenancy - Several applications will share the same hardware and software
- Resources can be shared but there should not be performance conflict between resources
- Multiple Apps will be running in parallel
- Spike in resource consumption of one app should not affect other application's performance
- SLA defined for performance need to be met for all hosted apps
- Applications will have projected capacity vs actual capacity
- Based on a ball park figure but actual load will be measure when the product is implemented
- Scale as you need
- Process several requests, Store Huge data, Analytics on top of data are offerings
More Detailed Architecture is explained in paper link
- Overview of Open Stack
- Apache Traffic Server used as caching proxy server
- Proxy (Route Traffic through intermediate steps)
- Reverse proxy vs Forward Proxy (Several Variations)
- Yahoo has 25K Clusters and 40K Servers
- Mobstor (Storage for large unstructured files)
- Sherpa (NOSQL solution from Yahoo)
Happy Learning!!!
