AWS, regions - global
-- 69 availability zones -- 22 geographic regions -- plans for 16 more availability zones and 5 more regions -- gartner recommended approach to running enterprise applications requiring high availability
IT Infrastructure - Key topics
-- components of IT infrasctructure -- major hw, storage, inputm and output technologies used in business and major hw trends -- major types of sw used in business and major sw trends -- principle issues in managing hw and sw technology -- how IT infrastructure is emerging towards the cloud -- aws overview
AWS web services
-- most comprehensive and broadly adopted cloud platform -- 175 individual serivces -- orgs use AWS services to reduce costs, become more agile, and innovate faster
SW Trends
-- open source sw (linux, apache) -- cloud-based sw and tools -- -- SaaS (Google Docs) -- Mashups (zip realty use of google maps & zillow) -- Apps (mobile apps)
Web Services
-- sw components that exchange info w/ one another using web comm stds and languages -- XML (foundation of web services) -- service-oriented architecture (SOA) -- collection of services used to build org's sw systems
Operating System SW
-- sw that controls computer activities -- GUIs and multi-touch PC operating systems -- -- windows -- mac -- unix -- linux mobile os -- -- chrome -- android -- ios
AWS, pay less by using more
-- users receive volume-based discounts/savings as usage increses -- tiered pricing -- -- the more you use, the less you pay
Cloud computing platform
AWS -- -- collection of services amazon provides users of its cloud platform -- largest provider of cloud-based services in the US
AWS, saving s for reserved resources
EC2, RDS -- reserved instances can result in savings up to 75% vs on-demand resources -- larger the upfront payment, the greater the discount
Infrastructure components
HW SW Data Management Networking Services
Types of computers
client/server -- -- form of distributed computing -- splits processing between clients and servers -- clients - use point of entry -- servers -- store and process shared data and perform network management activities
Contemporary Hardware Trends
cloud computing -- -- model of computing where computing resources accessed over the internet (IaaS, cloud platform as a service, SaaS) -- public and private clouds -- utility computing, on-demand computing -- data storage security is the responsibility of the service provider
Types of Computers
different sizes with varying capabilities for processing information -- -- personal computers -- mobile devices -- workstations
AWS, pay-as-you-go model
flexible, allows easy adaption to changing business needs while ensuring only needed resources are used
Infrastructure components, platform
for supporting all IS in the business -- -- computer hardware -- computer software -- data management technology -- networking and telecom technology -- technology services
Cloud computing platform
hw & sw capabilities provided as services over the internet provides access to applications and IT infrastructure anywhere at any time, using an internet-connected device
Storage, IO Technologies
input devices -- gather data and convert them into electronic form (keyboard, mouse, touch screen, pen, ...) output devices -- display data after they have been processed (monitor, printer, audio)
Contemporary hardware trends
mobile digital platform -- -- touch screen -- mobile devices, smartphone -- netbooks, tablets -- e-book readers consumerization of IT -- -- new tech that emerges in consumer market spreads into business orgs -- byod - business use of personal mobile devices
Types of computers
on-premise based compute cloud based compute
AWS, costs/payment
pay-as-you-go save $ when reserving resources economy of scale -- pay less for using more resources
AWS / cloud computing
pricing products global infrastructure
Application SW and Desktop Productivity Tools
programming languages for business -- -- c -- c++ -- visual basic -- java/c#
Major types of services
relationships between system sw, application sw, and users system sw -- os, language translators, utility programs application sw -- programming languages, fourth-gen languages, operate through system sw users - interacts with application sw
Why cloud infrastructure matters
secure extensive reliable AWS provides cloud infrastructure when and where it is needed largest and most dynamic ecosystem use cases across industries and sizes
Types of computers
servers -- -- support computer network, sharing files, and resources -- provide hardware platform for e-commerce mainframes -- -- large capacity, high-performance computers that process large amounts of data very rapidly -- used by airlines to handle thousands of reservations per second
Types of computers
supercomputer -- -- for rapid, complex calculations with thousands of variables -- engineering, scientific simulations, military/weapons research, weather forecasting grid computing -- -- geographically remote computers connected into a single network to act as "virtual supercomputer"
Contemporary Hardware Trends
virtualization -- -- process of presenting a set of computing resources that can be accessed in ways unrestricted by physical configuration or geographic location -- enables single physical resource to appear as multiple resources -- enables companies to host multiple systems on a single machine
