Architecture and Model

Architecture

  1. One codebase tracked in revision control, many deploys
  2. Explicitly declare and isolate dependencies
  3. Store config in the environment
  4. Treat backing services as attached resources
  5. Strictly separate build and run stages
  6. Execute the app as one or more stateless processes
  7. Export services via port binding
  8. Scale out via the process model
  9. Maximize robustness with fast startup and graceful shutdown
  10. Keep development, staging, and production as similar as possible
  11. Treat logs as event streams
  12. Run admin/management tasks as one-off processes

    • a tool to help turn minimally marked-up plain text into well formatted documents, including HTML, PDF (by way of LaTeX), OPML, or OpenDocument (specifically, Flat OpenDocument or ‘.fodt’, which can in turn be converted into RTF, Microsoft Word, or virtually any other word-processing format).
  • AsciiDoc
    • a text document format for writing notes, documentation, articles, books, ebooks, slideshows, web pages, man pages and blogs.

Performance Tuning

Counters

  • Typical performance counter collection
Counter Meaning Remarks
\Memory\Available Bytes available bytes
\Memory\Committed Bytes the private bytes committed to processes
\Process(process_name)\% Processor Time Processor Time = User Time + Privileged Time
\Process(process_name)\% Privileged Time the percentage of non-idle processor time spent executing code in privileged mode
\Process(process_name)\% User Time the percentage of time that the processor spent executing code in user mode
\Process(process_name)\Private Bytes bytes allocated exclusively for a specific process can be paged to disk or in the standby page list
\Process(process_name)\Working Set the shared and private bytes allocated to a process suddenly drop when you minimize an application
\Process(process_name)\Pool Nonpaged Bytes the number of bytes in the nonpaged pool, an area of system memory for objects that cannot be written to disk
\Process(process_name)\Pool Paged Bytes the number of bytes in the paged pool, an area of system memory for objects that can be written to disk
\Process(process_name)\Handle Count the total number of handles currently open by this process
\Process(process_name)\Thread Count the number of threads that were active in this process
\Process(process_name)\IO Read Bytes/sec the rate at which the process was reading bytes from I/O operations
\Process(process_name)\IO Write Bytes/sec the rate at which the process was writing bytes to I/O operations
\Network Interface(card_name)\Bytes Received/sec

      • used when accessing outer server
    • ~/.ssh/id_dsa, ~/.ssh/id_rsa

    • ~/.ssh/id_dsa.pub, ~/.ssh/id_rsa.pub
      • a public key of current account.

HTTP Basic Authentication

PKI

  • Public Key Infrastructure
  • Public key certificate
    • Certificate = Key + Subject + Digital Signature
  • Digital signature
    • key generation algorithm : generates a private key and a corresponding public key
    • signing algorithm : given a message and a private key, produces a signature
    • signature verifying algorithm : given the message, public key and signature, either accepts or rejects the message's claim to authenticity
