Target is struggling to compete with Amazon in retail, but finds other ways to defend itself.
The discount retailer reduces the use of Amazon Web Services, according to sources familiar with the matter, as the company aims to better control its infrastructure and stop financing its main rival. The purchase of Whole Foods by Amazon is the latest sign of the growth depth of the e-commerce giant in all forms of retail.
Microsoft Azure is one of the cloud providers competing with nab Target Business Cloud, sources said, who asked not to be named because the plans are confidential. Google and Oracle are strengthening their cloud offerings.
Like all big box stores, Target is disturbed by Amazon, which is selling more and more expensive and faster. Target's annual revenues are lower than five years ago, although the company sold its credit card and pharmacy business during this period, and the shares lost 23% market value in the last 12 months.
On Monday, Amazon finalized its $ 13.7 billion purchase of Whole Foods and instantly reduced store prices by more than 30 percent in fruit and organic meat. From electronics and household items to toiletries and grocery stores, Amazon is developing its inventory.
While there is little that Target can do to hamper Amazon's dominance in retail, the appearance of other cloud sellers allows the company to spend its computing and storage funds elsewhere. According to a source, Target plans to aggressively change e-commerce, mobile development and operations away from AWS until the end of the year and possibly until 2018.
A spokesman for Target said the company does not discuss the details of its dealings with vendors, but added that "we are currently using several cloud service providers and will continue to do so." An Amazon rep declined to comment.
Target hinted at its plans in October when the company said it had adopted an open source system called Spinnaker that Netflix has built to enable development teams to customize their clouds. A key component is that "Spinnaker was built to work with multiple public clouds compared to just one," Target said in an article posted on its website.
Target is not the only major retailer targeting AWS. The Wall Street Journal reported in June that Wal-Mart told its technology vendors not to run applications in the Amazon cloud and that for its own infrastructure the company uses a combination of servers and on-site services provided by Microsoft and others.
"If I use Azure or Google, I would go right after these guys," said John Vrionis, a partner at Lightspeed Venture Partners who supports the startup infrastructure. "I'm sure they could pack a convincing migration plan and these segments are probably very thirsty for it."
However, AWS has not yet seen a mass exodus.
In the second quarter, AWS controlled 34 percent of the cloud infrastructure market, covering Microsoft, IBM and Google combined, according to Synergy Research Group. Brands and stores such as Brooks Brothers, Nordstrom, Nike, Under Armor and Lululemon are AWS customers, although sources say that many retailers are considering other cloud providers.

HMRC's Switch to AWS Killed a Small UK Cloud Business
DataCentred, an exclusive British minnow, filed for bankruptcy after HMRC, its biggest client, broke a service contract in favor of an agreement with Amazon, the company recently accused by tax evasion parliamentarians.
DataCentred, based in Manchester, has signed an agreement with HMRC there for two years through the framework of the G-Cloud: its infrastructure OpenStack manages a critical system in the tax department, a contract that has supported 85% of the DataCentred invoicing.
However, The Register may reveal that six months ago, the firm was informed that the tax collector would no longer use its services because it reorganized the policy of being independent of the cloud to become an AWS fan.
DataCentred is not the only small cloud provider in the UK that has lost shares with HMRC as a result of the policy change. We know at least two more, although DataCentred appears to be the first direct victim
The company was founded by TeleCity founder Dr. Mike Kelly with £ 9 million funding from venture capitalist John Moulton and local authorities. The organization returned £ 1.2m in 2016, but sank red after losing the HMRC contract and entered the administration in August.
Readers of Reg will undoubtedly discuss the weaknesses of being overly dependent on a single customer, but also the irony of seeing HMRC pay for the services of AWS, a company sometimes criticized for its fiscal efficiency. .
Since Amazon and Microsoft set up local cloud operations in the UK several years ago, leasing storage space to other vendors in the AWS case, some Gov.uk personalities seem to have surrendered. his rhetoric of SMEs, deciding to work with technologies. giants after all.
The registry also found that the Ministry of Labor and Pensions has a policy of only purchasing public services in the Amazon cloud, Google or Microsoft. We asked the department to comment.
While there are compelling reasons for this decision, the question also arises whether Whitehall is swapping a group of major IT providers, known as "oligopoly" by former cabinet minister Francis Maude. - for another.
Such a move also seems to make redundant the G-Cloud IaaS, which has been put in place to provide small cloud service providers in the UK a level playing field for short-term government contracts.
The registry asked HMRC how their decision was in line with the government's promise to award contracts to SMEs; Has the department risked creating a new lockout by doing so? and whether the ministry can be perceived as a reward for corporate misconduct, because Amazon has often been criticized for avoiding taxes.
An HMRC spokesperson said: "We have discussed our long-term plans to provide cloud computing and what is best for our customers.
"The hyper-scale cloud technology is available again in the UK and the increased capacity of the cloud provides more robust services at a significantly lower cost to the taxpayer."
The ministry stated that it makes decisions about its suppliers through a fair and open process, and in accordance with the rules of the public service. Financial audits and regular tax compliance will be carried out as part of this process.
The European Commission recently ordered Amazon to repay € 250 million (£ 222 million) for illegal and unfair state aid from Luxembourg.
The Amazon group denied receiving special treatment and paid the full amount of the tax in accordance with international tax laws and Luxembourg.
The company, headed by Jeff Bezos, has also previously said it pays for all required taxes in the UK and in all countries where it operates.
"The corporate tax is based on profits and not on revenues, and our earnings have remained low as retail is a highly competitive and low margin business and we continue to invest heavily.

AWS Expands DOD IL4, Authentication Services
Agencies, military units and commandos now in the Ministry of Defense have more tools in their arsenal when it comes to integrating cloud services into daily operations.
The Defense Information Systems Agency has granted a temporary authorization for Amazon Web Services GovCloud to offer more than a dozen new cloud service applications under Tier 4. Impact AWS announced on the last job a blog entry on 26 of April.
In 2016, AWS has received DISA Provisional Authority to provide two services: Amazon's Amazon Elastic Compute Cloud and Simple Storage Service. The new IL-4 authorizations increase the number of bids to include AWS CloudFormation, Amazon Key Management Service, and Amazon redshift.
"CloudFormation is very important because it is an orchestration technology that allows you to automate, so rich, how to withstand a cloud environment and automate everything flows," said Mark Ryland, director of architecture solutions and chief architect of the World public sector by AWS teams. "[I] makes it less a manual procedure to use a cloud computing platform."
Although the DISA IL-4 permit facilitates the use of new services by AWS Department of Defense customers, this does not mean that they are automatically available for agency use.
"This announcement comes from a core group within the Department of Defense that created temporary permits, which means other groups within the Department of Defense can use," said M. Ryland. Users of the Department of Defense GovCloud "can take the document and analysis and granting the definitive authorization to operate."
In a separate blog post, AWS also announced multi-factor authentication capabilities for hardware-based GovCloud.
AWS has joined SurePassID, another digital security company, to implement the initiative, which will require users who log on to GovCloud to provide their user name and a password and authentication token code generated by the SurePassID.
The MFA tabs are stored in a different environment than the identity and access management in the GovCloud during the authentication process.
Ryland said that it is not supposed to replace the current GovCloud access cards through common access cards and personal identity verification cards. Instead, authentication-based tokens "fill the void" for agencies wishing to use GovCloud said Ryland. "This allows them to use a hardware token, but still get support from the MAE, which could be applicable in certain use cases."
Ryland describes the new features of the AMF plus a "edge case as a new critical capability" for GovCloud customers.

AWS Solutions Architect Professional: How to Get Ready!
As you probably already know, Amazon Web Services provides Amazon's, a set of certificates for products. Currently they include three different avenues for solutions architects, and sysops Administrators, and all of them on the basic level of certification, which Amazon calls "Associate level."
AWS Solutions offers professional certification engineers, architects and DevOps "AWS Certified Solutions Architect Professional" and "Certified Engineer DevOps AUG Professional" exam. Price for certification exam sit professional examinations professional level is $ 300 three hours. Does someone have a CV certification valuable.
I think you should really consider getting ready for these exams and certification leveraging their advantage. Most candidates do not have a certified AWS in this area, and should win help you to develop your career in the industry Cloud. An Associate level certification of income needed to access the professional level.
Getting ready to it
First things first: prepare and complete the Associate certification. This is required to access the professional level. You will need basic information about AWS products to get there.

Amazon’s AWS Results Give Rivals Cause to Worry
Amazon (AMZN) has questioned the doubts about its ability to continue business growth and large-scale cloud computing. The company said revenue from AWS (Amazon Web Services) increased 55% year over year (or every year) to $ 3.23 billion 3T16. The results easily exceed that required for the expected revenues of $ 3.170 billion for the cloud industry.
$ 10 billion in sales
The vertical axis shows the trend of AWS sales growth in the last five quarters. Amazon AWS expects revenues to reach $ 10 billion this year. In addition, revenue growth, margins in the Amazon cloud business improves. The company said operating profit margin rose to a record high of AWS 32% during the last quarter. The operating profit margin distribution of the clouds was 30% the same quarter last year.
The strong growth in AWS is a challenge to Microsoft (MSFT), Alphabet (GOOGL) and International Business Machines (IBM), because it means that they are more backward than the Amazon cloud in the battle in the IT market. Another cloud provider is struggling to steal market share of Amazon cloud computing is Oracle (ORCL). Because the AWS has become higher, some analysts have predicted that growth would slow down, but the last quarter is rejected Amazon these predictions.
Amazon has managed to surpass the expectations of growth in spite of its cloud division reports earlier this year that Apple (AAPL) has reduced its exposure to the AWS accept some operations to the cloud with Google Cloud alphabet.
Growth opportunities remain very important in the field of cloud computing, because the business transition to the cloud is still in its infancy.
3T16 earnings expectations
Overall, Amazon reported EPS (earnings per share) of $ 0.52 on revenue $ 32.7 billion 3T16 half. Although the result improved from the previous year, EPS could not reach consensus estimate, which called for $ 0.78. The consensus earnings forecast of 32.7 billion. Amazon seeks income between $ 42 billion $ 45.5 million on 4T16 against the consensus estimate of $ 44.6 billion.

Two Weeks Ago Salesforce Had an Outage. Now it's Outsourced to AWS
Fresh from his embarrassing incidents of data loss in North America, Salesforce announced that it will begin operating some software on Amazon Web Services.

AWS Certified Solution Architect Professional Dumps Questions
AWS Certified Solution Architect Professional Question 15
You have recently joined a startup company building sensors to measure street noise and air quality in urban areas. The company has been running a pilot deployment of around 100 sensors for 3 months each sensor uploads 1KB of sensor data every minute to a backend hosted on AWS.
During the pilot, you measured a peak or 10 IOPS on the database, and you stored an =average of 3GB of sensor data per month in the database.
The current deployment consists of a load - balanced auto scaled Ingestion layer using EC2 instances and a PostgreSQL RDS database with 500GB standard storage.
The pilot is considered a success and your CEO has managed to get the attention or some potential investors. The business plan requires a deployment of at least 1O0K sensors which needs to be supported by the backend. You also need to store sensor data for at least two years to be able to compare year over year Improvements.
To secure funding, you have to make sure that the platform meets these requirements and leaves room for further scaling. Which setup win meet the requirements?
A. Add an SQS queue to the ingestion layer to buffer writes to the RDS instance
B. Ingest data into a DynamoDB table and move old data to a Redshift cluster
C. Replace the RDS instance with a 6 node Redshift cluster with 96TB of storage
D. Keep the current architecture but upgrade RDS storage to 3TB and 10K provisioned IOPS
