10. 10 Its growth 100 X growth in developers. The crew is multiplying! and it has millions of lines of code, and a dozen projects. 10

11. 11 OpenStack Isn't Everything

12. 12 Virtual Machines and Storage

13. 13 Object Storage Key Features

14. 14 System Components The Ring: Mapping of names to entities (accounts, containers, objects) on disk.  Stores data based on zones, devices, partitions, and replicas  Weights can be used to balance the distribution of partitions  Used by the Proxy Server for many background processes Proxy Server: Request routing, exposes the public API Replication: Keep the system consistent, handle failures Updaters: Process failed or queued updates Auditors: Verify integrity of objects, containers, and accounts 14

15. 15 System Components (Cont.) Account Server: Handles listing of containers, stores as SQLite DB Container Server: Handles listing of objects, stores as SQLite DB Object Server: Blob storage server, metadata kept in xattrs, data in binary format  Recommended to run on XFS  Object location based on hash of name & timestamp 15

16. 16 Software Dependencies Object Storage should work on most Linux platforms with the following software (main build target for Austin release is Ubuntu 10.04):  Python 2.6  rsync 3.0 And the following python libraries:  Eventlet 0.9.8  WebOb 0.9.8  Setuptools  Simplejson  Xattr  Nose  Sphinx 16

20. Apache CloudStack

21. 21 IaaS…

22. 22 IaaS challenges Not out of the box by itself Need a farm of hypervisors  Xen, KVM, VMware… Need storage  For image catalogue  For volume/snapshot management Need flexible network that can be configured on-demand  VLANS, no VLANS, existing net infra, SDN…

23. 23 IaaS is really: A Data Center Orchestrator  Data storage  Data movement  Data processing That can:  Handle failures  Support large scale  Be programmed

24. 24 DevOps Bring your developers closer to the operations Make your sys admins develop the apps Move to Software Defined Data Center, Automate everything Dev: Java IDE Ops: Shell CLI

30. 30 CloudMonkey The CloudStack CLI, developed by Rohit Yadav ~600 lines of Python can be used both as an interactive shell and as a command line tool that simplifies CloudStack configuration and management. Lots of features:  Auto-completion  Tabular output  Help, scriptable, interactive shell…

32. 32 What is Open vSwitch Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag).Apache 2.0

33. 33 What is Virtualization Multiple virtual machines on the same physical host  Lowest layer is the hypervisor, which provides the illusion  Built by OS people  Historically, simple bridge Physical Switch

34. 34 Main Components

35. 35 Forwarding Components ovs-­vswitchd (Slow Path)  Forwarding logic (learning, mirroring, VLANs, and bonding)  Remote configuration and visibility openvswitch_mod.ko (Fast Path)  Packet lookup, modification, and forwarding  Tunnel encapsulation/decapsulation

36. 36 Centralized Control One OpenFlow connection per datapath  Exports idealized view of swtich’s datapath Lookup based on L2­ ‐ L4 Full wildcarding and priorities Actions: forward, drop, modify, and queue Missed flows go to central controller One management channel per system  Switch‐level configuration  Resources  Counters

60. 60 Introduction to Arduino Famous microcontroller manufacturers are MicroChip, Atmel, Intel, Analog devices, and more. It is a micro-computer. As any computer it has internal CPU, RAM, IOs interface. It is used for control purposes, and for data analysis. Micro-Controller:

61. 61 What is Arduino? 61 A microcontroller board, contains on-board power supply, USB port to communicate with PC, and an Atmel microcontroller chip. It simplify the process of creating any control system by providing the standard board that can be programmed and connected to the system without the need to any sophisticated PCB design and implementation. It is an open source hardware, any one can get the details of its design and modify it or make his own one himself.
