anton@ukdw.ac.idClient/Server
• In general, any application where multiple clients connect to a single server.
client1 client2 client3
server • one client program (most typical)
or
– May each act as client, server or both
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

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,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

What is Cloud Computing ?
the Fifth Generation of Computing
(after Mainframe, Personal Computer, Client-Server Computing, and the web)p g )
Cloud Computing is…
… virtualized compute power and storage
delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet.
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….
• Using TCP port 80 (default)
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

Service Oriented Architecture
• SOA adalah sebuah konsep Software
Architecture yang mendefinisikan penggunaan
layanan untuk mendukung kebutuhan
pengguna software.
• AA servicei -oriented architecture is a framework i t d hit t i f k
•
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 dikirimkan/diterima oleh siapapun
– SOA memisahkan antara bagian publik dan bagian privat
• Bagian publik dapat diakses oleh siapapun, berupa deskripsi tentang layanan yang ditawarkan
SOA SOA SOA SOA
• Services can be discovered
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 Composable Composable SOA SOA SOA SOA Interoperable Interoperable Loosely Loosely Coupled Coupled Re Re--UsableUsable

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

Web Service Layer
• Service transport
• XML messaging dan encoding/decoding
• Service description
• SOAP meru akan format untuk men irimkan
SOAP (Simple Object Access Protocol)
• SOAP merupakan protokol komunikasi
berbasis XML yang memperbolehkan aplikasi saling bertukar informasi melalui HTTP
• SOAP merupakan format untuk mengirimkan p g message melalui Internet, bersifat platform independent, language independent, dan merupakan standar W3C
• SOAP membungkus request & response dalam XML
(wajib)
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

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 byy Royy
Fielding (a principal author of HTTP 1.0 dan 1.1
protocol)
• RESTful URLs are addressable
