Physical Architecture
Four Components of a Computer System
Tightly coupled
Loosely Coupled
Client/Server In general, any application where multiple clients connect to a single server. client1 client2 client3 server one client program (most typical) or multiple client programs
Generic Client/Server Architecture
Peer-to-Peer Computing Another model of distributed system P2P does not distinguish clients and servers Instead all nodes are considered peers May each act as client, server or both Node must join P2P network Registers its service with central lookup service on network, or Broadcast request for service and respond to requests for service via discovery protocol Examples include Napster and Gnutella
What is Cluster? A cluster is a type of parallel and distributed processing system, which consists of a collection of interconnected stand-alone computers cooperatively working together as a single, integrated computing resource. A node a single or multiprocessor system with memory, I/O facilities, & OS A cluster generally 2 or more computers (nodes) connected together in a single cabinet, or physically separated & connected via a LAN appear as a single system to users and applications

What is Cloud Computing? the Fifth Generation of Computing (after Mainframe, Personal Computer, Client-Server Computing, and the web)
Cloud Computing is virtualized compute power and storage delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet. These shared, on-demand IT resources, are created and disposed of efficiently, are dynamically scalable through a variety of programmatic interfaces and are billed variably based on measurable usage.
Internet & Web Architecture
Protokol Web: HTTP Hypertext Transport Protocol (RFC 1945) Oleh Tim Berners-Lee, 1990 Protocol that used to communicate between web browsers and web servers Using TCP port 80(default) This protocol supports hypermedia files HTTP 1.0 becomes 1.1 by IETF (RFC 2616)
HTTP Message
N-tier web architectures HTML rendering Templates, HTML generation scripts, XML and XSLT Application-specific components and application logic Domain-specific and database-independent layer, typically object-oriented Data storage, typically an (SQL) RDBMS Client Presentation Business Logic Data Access Data
Service Oriented Architecture SOA adalah sebuah konsep Software Architecture yang mendefinisikan penggunaan layanan untuk mendukung kebutuhan pengguna software. A servce-oren service -oriented e architecture t is sa framework for integrating business processes and supporting IT infrastructure as secure, standardized components services that can be reused and combined to address changing business priorities
SOA dan Integrasi Aplikasi/Sistem SOA sebagai platform integrasi: SOA memisahkan antara pesan/query/call dengan pemrosesan Pesan/query/call distandardisasi dan tidak dikaitkan dengan sebuah produk teknologi tertentu, sehingga bisa dikirimkan/diterima oleh siapapun SOA memisahkan antara bagian publik dan bagian privat Bagian publik dapat diakses oleh siapapun, berupa deskripsi tentang layanan yang ditawarkan Bagian privat hanya bisa diakses oleh pemilik/penyedia layanan
Characteristics of SOA Services have platform independent, self describing interfaces (XML) Messages are formally defined Services can be discovered Services have quality of service characteristics defined in policies Services can be provided on any platform Interoperable Composable SOA Loosely Coupled Re-Usable
SOA implementation : Web Service Mempertukarkan data dalam format XML. Tersedia dan dikomunikasikan melalui Internet atau intranet. Bersifat operating system/programming language independent. Web service mempertukarkan data antara service requestor (aplikasi yang menggunakan data/service) dan service provider (server penyedia data/service) menggunakan service registry (yang berisi kumpulan service-service), dengan salah satu teknologi: XML-RPC SOAP REST
Web Service Layer Service transport XML messaging dan encoding/decoding Service description Service discovery
SOAP (Simple Object Access Protocol) SOAP merupakan protokol komunikasi berbasis XML yang memperbolehkan aplikasi saling bertukar informasi melalui HTTP SOAP merupakan format untuk mengirimkan message melalui Internet, bersifat platform independent, language independent, dan merupakan standar W3C SOAP membungkus request & response dalam XML
Elemen SOAP Elemen Envelope yang mengidentifikasi XML dokumen sebagai SOAP message (wajib) Elemen Header yang berisi informasi header (opsional) Elemen Body yang berisi informasi call dan response (wajib) Elemen Fault yang berisi informasi error yang terjadi (opsional)
What is REST? REST stands for Representation State Transfer REST is about accessing resources through a universal interface (HTTP murni) Conceived in 2000 as a doctoral dissertation by Roy Fielding (a principal author of HTTP 1.0 dan 1.1 protocol) RESTful URLs are addressable Sample: http://www.mysite.com/products/trek8300 Links to related data
RESTful Web Services URL HTTP Request PUT XML JSON DELETE Resources Res 1 GET Res 2 POST Res 3 HTTP Response Status Payload XML JSON Res 4
