A mazon W eb Services^(S) ( AWS ) er blevet udråbt som verdens mest omfattende og bredt vedtagne cloud-platform, og er blevet en gigantisk komponent i Amazons forretningsportefølje. Ligesom ^(Just)Amazon.com har rystet op i onlinehandelsområdet, har AWS rystet computerverdenen op.

Amazon Web Services består af flere cloud computing-produkter og -tjenester såsom servere, storage og netværk, og er blevet frontløber for cloud computing-platforme og overskygger konkurrenter som Microsoft Azure .

Kort sagt, AWS er en cash cow for Amazon . Men hvad er Amazon Web Services helt præcist? Hvad i alverden er cloud computing?

Hvad er Amazon Web Services?^{(What Is Amazon Web Services?)}

Et datterselskab af Amazon.com , Amazon Web Services ( AWS ) tilbyder overkommelige cloud-computing-tjenester med evnen til at gøre sin kundebase stærk fra små virksomheder som Pinterest til store virksomheder som D-Link .

Cloud computing er brugen af fjernservere på internettet til at gemme, administrere og behandle data i stedet for en lokal server eller personlig computer. Cloud computing kommer i tre grundlæggende kategorier begyndende med Software as a Service ( SaaS ), som reducerer virksomhedens udgifter ved at levere en cloud-server med software, der allerede er inkluderet.

Platform as a Service ( PaaS ) lader udviklere bygge apps og samarbejde om forskellige projekter uden at skulle købe eller vedligeholde infrastruktur.

Sidst har vi Infrastructure as a Service ( IaaS ), som er hvad AWS falder ind under mere end de andre. IaaS giver virksomheder mulighed for at leje servere, storage, sikkerhed osv. fra en cloud-udbyder.

Amazon Web Services' tjenester^{(Amazon Web Services’ Services)}

Amazon Web Services giver kunderne en bred vifte af cloud-tjenester. Nogle af de tilbudte muligheder er Amazon E lastic C ompute C loud (EC2), Amazon Simple S torage Service (S3), Amazon V irtual P^(S) rivate C ^(S)loud ^(V)(^(P) VPC )^(C) , Amazon^(VPC) SimpleDB og^{(Amazon SimpleDB)} Amazon WorkSpaces^{(Amazon WorkSpaces)} .

Amazon EC2 leverer virtuelle computermiljøer, der tilbyder overkommelig skalerbar computerkapacitet i AWS - skyen. EC2 eliminerer behovet for at investere i hardware, hvilket gør det muligt for kunderne at udvikle og implementere apps i en hurtigere hastighed.
Amazon S3 bruges til lagring og hentning af data, til enhver tid, fra hvor som helst i verden på nettet. Det er en pålidelig, skalerbar og billig datalagringsinfrastruktur, der kommer større virksomheder til gode.
Amazon VPC er et virtuelt datacenterlignende netværk defineret af dig, som bruger den skalerbare infrastruktur fra AWS . Med Amazon VPC kan du starte dine ressourcer i AWS -miljøet i dette virtuelle netværk uden at skulle købe software eller infrastruktur.
Amazon SimpleDB er et NoSQL -datalager til at aflaste arbejdet med databaseadministration. En udvikler kan gemme og forespørge på forskellige dataelementer via webserviceanmodning med den afhængighed, at SimpleDB vil fuldføre arbejdet.
Amazon WorkSpaces fungerer som en anden form for cloud computing, Desktop as a Service ( DaaS ). Med dette får du en sikker desktopløsning, der enten bruger et Windows- eller Linux -operativsystem. Denne service kan derefter skaleres til at levere virtuelle desktops til arbejdere over hele verden.

Fordelene ved AWS^{(The Benefits of AWS)}

Koste^(Cost)

Virksomheder plejede at skulle fysisk bygge et lagerplads for selv at kunne opbevare store mængder data og vedligeholde det. Valget af at gemme data i skyen kom til at koste betydelige omkostninger oven i lange kontrakter, der havde potentialet til at hindre virksomhedens vækst. At købe mere plads end nødvendigt kan blive for dyrt, mens køb af for lidt kan vise sig at være katastrofalt.

Det samme princip gjaldt for computerkraft. At opretholde forretningen i spidsbelastningsperioder krævede, at virksomhederne købte mere strøm. Problemet var i lav-spidsbelastningsperioder, hvor strømmen ikke længere var påkrævet. Virksomheden skulle stadig betale for strøm, de ikke engang brugte.

AWS tillader virksomheder kun at betale for det, de bruger. Uden forhåndsomkostninger på lager og infrastruktur er der ikke længere behov for at estimere brug i forhold til omkostninger. AWS skalerer omkostninger automatisk til kundernes behov.

Skalerbarhed^{(Scalability)}

Nystartede virksomheder^(Start-ups) og små virksomheder får åbenlyse fordele ved den skalerbarhed, som Amazon Web Services tilbyder. Prisen ændres baseret på kundernes brug, hvilket gør AWS til et godt valg til at bygge en virksomhed nedefra og op. Denne virksomhed vil modtage alle de værktøjer, der er nødvendige for at opbygge en start-up med skyen.

Allerede etablerede virksomheder vil drage fordel af Amazons billige migrationstjenester, der tillader en problemfri flytning af infrastrukturen til AWS .

AWS fortsætter med at levere ressourcer til støtte for ekspansion, efterhånden som en virksomhed fortsætter med at vokse takket være en fleksibel forretningsmodel. Kunder^(Customers) behøver ikke længere at gense en diskussion om, hvorvidt deres nuværende budget for computerbrug er nødvendigt. Under nogle omstændigheder, når det drejer sig om AWS ’s skalerbarhed, kan en virksomhed bruge AWS til at "indstille det og glemme det."

Sikkerhed og pålidelighed^{(Security and Reliability)}

AWS har servere placeret inden for 76 tilgængelighedszoner, der spænder over 245 lande og territorier. Disse zoner er blevet opdelt ikke kun for at give brugerne mulighed for at sætte geografiske begrænsninger på deres tjenester, men også for at diversificere fysiske placeringer, give stærkere sikkerhed og undgå permanent datatab på verdensplan.

Hvert datacenter over hele kloden vedligeholdes og overvåges løbende. Amazon Web Services er uden tvivl meget mere sikker end en virksomhed, der hoster sit eget websted eller lager. Dette skyldes, at lokalisering af data på et enkelt, let identificerbart sted kan vise sig at være sårbart.

AWS giver kun adgang til dets fysiske datacentre på et væsentligt grundlag. Dette, udover at holde disse steder skjult for offentligheden, skaber en stærkere barriere for fysiske indtrængen. Afbrydelser og potentielle serverangreb er også sikrere takket være Amazons erfaring med cloud-tjenester. Den tunge overvågning døgnet rundt gør det så ethvert angreb hurtigt kan identificeres og håndteres af en enkelt it-specialist.

Valg af Amazon Web Services^{(Choosing Amazon Web Services)}

Bygget af en global leder inden for online detailhandel, fjerner Amazon Web Services det gættearbejde og den videnskabelige analyse, der kræves for at identificere dine infrastrukturbehov. Den fleksible betal-per-brug-model høster fordele for startups, der har behov for en billigere startmulighed. Mens mangeårige eksisterende virksomheder fortsætter med at udvide med hundreder og tusinder af kunder, der udnytter AWS i over 190 lande.

Uddannelsen og certificeringen af AWS er også blevet en meget efterspurgt og efterspurgt validering af fagfolk og organisationer, der har behov for innovative teams til cloud-initiativer.

AWS er ikke uden sine ulemper, idet den primært beskæftiger sig med EC2's region til region standard ressourcegrænser og andre generelle cloud computing-problemer som servernedetid og begrænset kontrol.

Uanset hvad, giver valget af Amazon Web Services nem at bruge cloud computing uden kapacitetsbegrænsninger på en omkostningseffektiv, pålidelig og sikker platform.

HDG Explains : What Is (AWS) Amazon Web Services?

Touted as the world’s most comprehensivе and broadlу adopted cloud platform, Amazon Web Services (AWS) has become a giant component of Amazon’s business portfolio. Just as Amazon.com has shaken up the online retail space, AWS has shaken up the world of computing.

Comprising multiple cloud computing products and services such as servers, storage, and networking, Amazon Web Services has become the frontrunner for cloud computing platforms, overshadowing competitors like Microsoft Azure.

In short, AWS is a cash cow for Amazon. But what is Amazon Web Services exactly? What in the world is cloud computing?

What Is Amazon Web Services?

A subsidiary of Amazon.com, Amazon Web Services (AWS) offers affordable cloud-computing services with the power to make its customer base strong from small scale companies like Pinterest to big enterprises like D-Link.

Cloud computing is the use of remote servers on the internet to store, manage and process data rather than a local server or personal computer. Cloud computing comes in three basic categories beginning with Software as a Service (SaaS) which reduces company expenditure by providing a cloud server with software already included.

Platform as a Service (PaaS) lets developers build apps and collaborate on various projects without the need to purchase or maintain infrastructure.

Last, we have Infrastructure as a Service (IaaS) which is what AWS falls under more so than the others. IaaS provides companies the chance to rent servers, storage, security, etc. from a cloud provider.

Amazon Web Services’ Services

Amazon Web Services provides customers with a wide array of cloud services. Some of the options offered are Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), Amazon Virtual Private Cloud (VPC), Amazon SimpleDB and Amazon WorkSpaces.

Amazon EC2 provides virtual computing environments offering affordable scalable computing capacity in the AWS cloud. EC2 eliminates the need to invest in hardware, enabling customers to develop and deploy apps at a faster rate.
Amazon S3 is used in the storage and retrieval of data, at any time, from anywhere in the world on the web. It’s a reliable, scalable, and inexpensive data storage infrastructure that benefits larger businesses.
Amazon VPC is a virtual data center-like network defined by you which uses the scalable infrastructure of AWS. With Amazon VPC, you can launch your resources kept within the AWS environment into this virtual network without the need to purchase software or infrastructure.
Amazon SimpleDB is a NoSQL data store for offloading the work of database administration. A developer can store and query different data items via web services request with the reliance that SimpleDB will complete the work.
Amazon WorkSpaces works as another form of cloud computing, Desktop as a Service (DaaS). With this, you receive a secure desktop solution using either a Windows or Linux operating system. This service can then be scaled to provide virtual desktops to workers all over the world.

The Benefits of AWS

Cost

Companies used to have to physically build a storage space in order to store large amounts of data and maintain it themselves. Choosing to store data on the cloud came at considerable expense on top of lengthy contracts that had the potential to hinder company growth. Purchasing more space than needed could become too expensive, while purchasing too little could prove disastrous.

The same principle applied to computing power. Sustaining business at peak times required that companies buy more power. The problem was during off-peak times when the power was no longer required. The company would still have to pay for power they weren’t even using.

AWS allows companies to only pay for what they use. With no upfront costs on storage and infrastructure, there is no longer a need to estimate usage versus cost. AWS scales cost automatically to the needs of its customers.

Scalability

Start-ups and small businesses receive obvious benefits from the scalability that Amazon Web Services offers. The cost is modified based on the customers’ usage, making AWS a great choice for building a business from the bottom up. That business will receive all the tools necessary to build a start up with the cloud.

Already established businesses will benefit from Amazon’s low-cost migration services allowing a seamless move of infrastructure over to AWS.

AWS continues to provide resources in aid of expansion as a business continues to grow thanks to a flexible usage business model. Customers no longer need to revisit a discussion about whether their current budget for computer usage is necessary. In some circumstances when pertaining to AWS’s scalability, a company can use AWS to “set it and forget it.”

Security and Reliability

AWS has servers located within 76 availability zones, spanning 245 countries and territories. These zones have been divided not only to give users a choice in setting geographical limits on their services, but also to diversify physical locations, providing stronger security and avoiding permanent data loss worldwide.

Every data center across the globe is maintained and continuously monitored. Arguably, Amazon Web Services is much more secure than a company hosting its own website or storage. This is because the localization of data in a single, easily identifiable location could prove vulnerable.

AWS allows access to its physical data centers on an essential basis only. This, on top of keeping these locations hidden from the public, creates a stronger barrier to physical intrusions. Outages and potential server attacks are also safer thanks to Amazon’s experience with cloud services. The round the clock heavy monitoring makes it so that any attack can be quickly identified and dealt with by a single IT specialist.

Choosing Amazon Web Services

Built by a global leader in online retail, Amazon Web Services removes the guess-work and scientific analysis required to identify your infrastructure needs. The flexible pay-per-use model reaps benefits for startups in need of a cheaper starting option. While longtime existing businesses continue to expand with hundreds and thousands of customers leveraging AWS in over 190 countries.

The training and certification of AWS has also become a much sought after and high in-demand validation by professionals and organizations in need of innovative teams for cloud initiatives.

AWS is not without its disadvantages, primarily dealing with EC2’s region to region default resource limits and other general cloud computing issues like server downtime and limited control.

Regardless, choosing Amazon Web Services provides easy-to-use cloud computing with no capacity limits on a cost-effective, reliable and secure platform.
