The Internet provides new challenges and opportunities for the integration, representation, dissemination, and communication of geographic information.
Everyday the Internet is becoming more important in our lives
Today I shop, get traffic conditions, compare products, buy tickets, and read product reviews Today I can't find restaurants in my area that serve a particular cuisine that can take a reservation at 7PM Today a business can't find a vendor that has an item in stock or which vendor is cheapest or which can ship it to me the soonest

Getting information in the right place at the right time means getting it anywhere and anytime. Information service delivery expectations and models increasingly call for 24 hour / 7 day a week access for clients and partners.
Sentralisasi data, aplikasi, dan pemrosesan data mell. internet yang bisa diakses oleh berbagai device
• A new trend in information technology, moving software from personal computers to the Internet • Popular cloud systems include: Flickr, Google Docs and Amazon Cloud Drive. They perform the functions that were traditionally done with software installed on personal computers.
• Put data and software, which are used to be on personal computers, to a giant centralized computer system. This form is called cloud computing. The centralized system is called a cloud system.
You rent cloud services, such as photo editing, managing and sharing, from them, the same way as you rent textbooks from bookstores Cloud services is the use of computer resources in cloud systems

The term "cloud" is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network http://www.gartner.com/it/page.jsp?id=707508
The concept of cloud computing dates back to 1961, when Prof. John MacCarthy predicted that “computation may someday be organized as a public utility.” http://www.complush.com/internet-network-connection/
In 1991, Salesforce.com, one of the first movers in cloud computing, introduced the concept of delivering enterprise applications via a simple website
In 2002, Amazon Web Service was launched
Google brought cloud computing to the forefront of public consciousness by introducing Google Docs in 2006 http://www.cloudtweaks.com/2011/02/a-history-of-cloud-computing/
• In the following years, IBM, Microsoft, Oracle and a host of companies joined cloud computing

Dalam kerjanya komputasi modern menghitung dan mencari solusi dari masalah yang ada, dan perhitungan yang dilakukan itu meliputi: 1. Akurasi (big, Floating point) 2. Kecepatan (dalam satuan Hz) 3. Problem Volume Besar (Down Sizzing atau pararel) 4. Modeling (NN/Neural Network & GA/ Genetic Algorithm) 5. Kompleksitas (Menggunakan Teori big O)

Mobile Computing atau Komputasi Bergerak. Mobile computing (komputasi bergerak) merupakan kemajuan teknologi komputer sehingga dapat berkomunikasi menggunakan jaringan tanpa menggunakan kabel serta mudah dibawa atau berpindah tempat, tetapi berbeda dengan komputasi nirkabel.
Grid Computing. Komputasi grid memanfaatkan kekuatan pengolahan idle berbagai unit komputer, dan menggunakan kekuatan proses untuk menghitung satu pekerjaan. Cloud Computing atau Komputasi Awan. Komputasi awan adalah sebuah paradigm baru dari konsep yang sebenarnya sudah ada. Beberapa aplikasi yang sangat akrab dari cloud computing adalah icloud (produk dari Apple) dimana user menyimpan data-data phonebook mereka di server Apple, bukan lagi di handphone mereka.

1. Komputer-komputer penyedia sumber daya bersifat heterogenous karena terdiri dari berbagai jenis perangkat keras, sistem operasi, serta aplikasi yang terpasang. 2. Komputer-komputer terhubung ke jaringan yang luas dengan kapasitas bandwidth yang beragam.
3. Komputer maupun jaringan tidak terdedikasi, bisa hidup atau mati sewaktu-waktu tanpa jadwal yang jelas.
Email yang tersedia dalam bentuk web mail merupakan contoh yang sangat kecil dari teknologi cloud computing.
1. Google Drive yang didukung oleh Google (15 GB), 2. Dropbox yang didukung oleh Facebook (2 GB) 3. OneDrive yang didukung oleh Microsoft (7 GB + 5 GB jika mengajak teman-teman) 4. iCloud yang didukung oleh Apple (5 GB) .

A personal assistant app comes with iPhone 4S. You can use your voice to send messages, schedule meetings and place phone calls.
Know the score. Ask Siri for baseball, basketball, football, hockey, and soccer scores as well as schedules, rosters, and stats. Choose a movie. Ask Siri to get showtimes, buy tickets from Fandango, look up movie facts, play trailers, show you reviews, and more.
Find a restaurant. Ask Siri to search by different criteria or a combination. Siri gets you photos, reviews, and reservations.

Multi-tenancy ◦ Resources in cloud systems can be shared among a large number of users. ◦ Improve the efficiency of cloud systems and save cost for cloud service providers.
• Scalability – Even when the total work load for a cloud system increases dramatically, the system could improve its capacity by adding more hardware to handle the increased load effectively
• Elasticity – A cloud system only delivers the minimum amount of computing resources that meet users’ need. The amount of resources provided to users increase when they need more, and decrease when they need less. Users only pay for whatever they consumed.
Device independent ◦ Users can utilize cloud services using whatever device they have, should it be a laptop, an iPad or a smartphone, as long as they have access to the Internet.
Low-cost ◦ Computing resources are provided by cloud systems. Users do not need to purchase expensive computers to perform tasks that need high performance computing.
◦ If you do not want to keep a book, why don’t you rent the book from the UB bookstore or borrow one from the UB library? So you only spend a fraction of the cost of buying the book.
Reliability ◦ Multiple redundant sites are used in cloud systems. There are always backups available when one or more sites are down.

(pro et contra)
adalah layanan yang menyediakan modul siap pakai; yang digunakan untuk mengembangkan aplikasi, berjalan diatas platform tersebut.
LAINNYA: game di Facebook, Google Android, Apple i-Tunes, dsb.
(pro et contra)
adalah layanan yang "menyewakan" sumberdaya teknologi informasi dasar, yang meliputi media penyimpanan, processing power, memory, sistem operasi, kapasitas jaringan dll, yang digunakan untuk menjalankan aplikasi.
Kelebihan cloud computing : 1. Lebih murah, karena kita tidak perlu menyediakan infrastruktur & SDM TI sendiri. 2. Lebih reliabel, karena data dan apikasi kita dijaga oleh layanan tanpa henti 24x7.
3. Lebih efisien, karena kita bisa memilih layanan yang kita butuhkan dan membayar sesuai dengan biaya layanan itu saja. 4. Lebih kompatibel, karena dapat diakses dimana saja asal ada koneksi internet. 5. Lebih aman, karena seluruh data disimpan dalam sebuah server terpusat yang memiliki fungsi backup.
6. Lebih sederhana, karena kita tidak memerlukan pemahaman sistem TI.
Kekurangan Cloud Computing Komputer akan menjadi lambat atau tidak bisa dipakai sama sekali jika internet bermasalah atau kelebihan beban. Dan juga perusahaan yang menyewa layanan dari cloud computing tidak punya akses langsung ke sumber daya. Jadi, semua tergantung dari kondisi vendor/penyedia layanan cloud computing. Jika server vendor rusak atau punya layanan backup yang buruk, maka perusahaan akan mengalami kerugian besar.
