AWS Launches Relational Database Migration Service

After a brief period m test that the client migrate viewed Los Mas 1,000 bases in situ data cloud, AWS has officially launched its base Data Migration Service. This is application-compatible with service cloud Live Migration Scenarios and clients who want to spend their DATABASE platform in the context of migration can, thanks to a free conversion tool pattern.

Amazon know the service took a fall in its annual Past re: Invent Conference offers to customers and a limited preview In A AWS region. Now based Data Migration Services (DMS) is open to ALL guests and is available in eight World Regions AWS. In a blog post announcing the general availability of AWS Evangelist Jeff Barr boss how to describe this Management Service works.

"The database AWS Migration Service works by creating management and replication instance in AWS. This instance Data Download source database and loaded into the target database, and can be used for a single Followed Migration replication continued to give today a whole Migration that involves a minimum of time. in DMS handles many complex details related to migration, type data Transformation conversion and Manner basis including the data Platform to Other (Oracle in Aurora, by . example) the service also monitors and Health replication instance, if advised by something goes wrong, there is automatically an instance: provisions replacement if necessary "

ALTHOUGH A DMS test has yet to be AWS - it is running in a virtual machine EC2 or basic relational Data Service (RDS) - The other end may be located in an accessible host. The replication instance is among the endpoints and manages the Secure Data. DMS Can Be As One-use or sea for Migration and continued replication between databases. Configure the migration task, the user chooses "Being A full load of existing data, a full load of data and ongoing changes m or just a replica of the ongoing changes m." DMS works with a wide range of data relational databases, there Peer to Peer Support to Migration, migration platform or another.

"Service Data Base AWS Migration Can Be As used for Oracle, SQL Server, PostgreSQL, Amazon Aurora, MySQL, or Migration MariaDB. The service supports smooth migration as Oracle Oracle is heterogeneous between migration platforms different databases As Oracle Amazon Aurora or SQL Server to MySQL service data migration database. AWS can migrate databases situ on Amazon RDS or Amazon EC2, "the databases if running on EC2 RDS or vice versa as well One database to migrate another RDS RDS database."

What USING engine database is the source or destination, the user has no drivers to install or Hall DMS software para works locally and correctly. Amazon pisteytetty Surprised by the frequency with which the customer has been the Migration exists Both Basic Information Change engine s also more open position.

"Hundreds of customers is moved over a thousand your data base in situ Amazon Aurora, Other engines Amazon RDS or current databases if running on Amazon EC2 in the previous view of the DATABASE Migration Service AWS" said Hal Berenson, relational basic VP data Services, AWS. "customers have our repeatedly said they wanted faire un database engine YOUR AWS dATA site, and is also esta moving the basic engine options More open data But the response to the basic data Service AWS Migration FUE. Even stronger than expected in the survey, a third of Migration data base USING database AWS Service paragraph Migration mover No Solo the databases AWS cloud, but also change bases paragraph data Processing Engines in Him. "

Customers who decide to migrate to a platform DATABASE, it is said that no business using the tool conversion schemes for the AWS convert source schema and format: stored procedures appropriate destination. Specifically, Microsoft SQL Server and sea or Oracle Schema source formats and converts them if they run on the Amazon RDS instances based on PostgreSQL, Aurora, or MySQL. This conversion tool Free Functions As in the client software Windows, OS X, Linux or workstations.

Amazon is positioning esta As a form DMS affordable to migrate data. There is no cost m For Migration own software, is that customers must pay the cost of replication instance. These bodies replication "includes ample storage space for swap space, replication logs, and hidden data, most of replication exists Input data transfer is free." Two types of hay available for replication instance EC2 Instances welcome .. T2 T2 is a C4 offers Consumption and moderate burstable CPU Performance Amazon Recommends paragraph USE THESE develop there ProBAR Migration Migration periodic tasks or C4. For high performance and Baja not recommended for use in large databases latency. An instance T2 comes with 50 GB of storage in red, and red C4 cases includes 100GB storage. It costs $ 0.115 GB per month (US) for extra storage. DMS supports up to 6TB Storage para all instances of replication in a statement. De While the incoming transfer still Facts esta available, and transfers between data free bases, customers Same Area Availability of AWS if they transfer between Availability Zones, The AWS Regions, or environments Outdoor Habra by loading GB .

DMS user can migrate all tables in a source database or just a subset of tables. As you can imagine, hay About Warnings compatibility features for Oracle (source, destination), SQL Server (source, destination), PostgreSQL (source) and MySQL (source, destination) Migration of databases. Interestingly, sources of data are encrypted there is no problem DMS para.

"Basic Migration Data Service AWS Connect has Configuracion DATABASE Layer SQL Interface If you USING. Functions transparently encrypt data SQL Server or Oracle, the basic service Data Migration AWS will be able to extract the data decrypted These sources and replicated to the target m.

What An AAPL Loss Means for AWS & Amazon.com, Inc. Stock

Amazon available recent decline illustrates why it is such a risky investment

During the last two days of this week, more than $ 10 billion in market capitalization increased from Amazon.com, Inc. (AMZN). Ironically, the markets reached their highest 2016 these days.

What a waste of AWS AAPL Media & amp; Amazon.com, Inc. The reason for the loss of Amazon shares was a report of the CRN technology site Apple Inc. (AAPL) takes its cloud infrastructure business (LAAS) elsewhere, specifically Alphabet Inc (GOOG , GOOGL).

Amazon Web Services or AWS, played a key role in supporting Apple's iCloud and other cloud-based services for years. Reportedly, AAPL spends about $ 1 billion per year in AWS.
Therefore, if AWS reality loses its relationship with Apple, Amazon shares could fall further? Or, is the loss and AMZN prices?

The Loss Means for AAPL AWS

First, the report suggests that AAPL spends about $ 400 million to $ 600 on Google cloud platform, which means that it remains a customer of AWS. So if this story is true, AMZN AAPL is not lost completely.

Bernstein Research estimates that AWS will grow 57% in 2016, reaching revenues of $ 12.4 billion. If AWS lose this activity, the growth rate is still an impressive 50% to 52%. When you consider these facts, the $ 10 million that Amazon stock has lost the last weekend of value takes into account the loss of Apple - which, incidentally, is only a rumor. We can not forget that the sources of CRN can be wrong.

A Major Problem for Amazon Stock

Although Amazon has probably provided most of their beats with the possible loss of AAPL as a client, the reaction of investors underscores a much larger problem. Such is the reliance on Amazon available on the performance of AWS and how quickly speculation may push lower.

Note, AMZN should create almost $ 130 billion in revenue in 2016. This means that AWS will represent less than 10% of total sales. However, it might well be worth half the $ 250 billion, market capitalization of Amazon, maybe more.

In April last year, I explained that AWS could be worth more than $ 85 million on the open market as an autonomous entity. This came after Amazon reported earnings of AWS, and its performance has released much higher profitability and faster as investors and analysts expected growth.

Since then, revenues and margins AWS rose even faster. Therefore, it is very possible that AWS is worth $ 125 billion to Amazon securities. If we assume that AWS can maintain close to 29% operating margin, a valuation of $ 125 trillion implies a price-FY2016-sale price of 10 and a benefit / FY2016 operating under 35s.

However, with such valuation related and well for the future of AWS AWS Amazon it is speculative, a perfect storm for risk of loss in case of bad press, or the disappointing results is created. The fact is that AWS may have captured more than 70% of new revenue "quota continuous flow" in Q4, according to Bernstein, but the likes of Google, Microsoft Corporation (MSFT) and International Business Machines Corp. (IBM) are all coming on strong.

Yes, AWS has much more capacity and is much bigger than any of its competitors, but as prices become more aggressive and competitors invest to increase capacity, AWS is likely to lose some customers over time.

And because of its valuation, investors should expect more days where billions of market capitalization eradicated in response to rumors, true or not, related to AWS.

Why AWS dominates the cloud services market

In the latest report published by Gartner Magic Quadrant last year, Amazon Web Services (AWS) has maintained its position as the king of cloud Infrastructure as providers of a service (IaaS). Followed by Microsoft Azure and Google Cloud Platform, the three cloud providers often called "Hyperscale suppliers.

What was more surprising was the news that AWS had more than 10 times the computing capacity utilization the next 14 largest companies mixed cloud.

In addition, AWS announced a measure that was difficult to combat: More than 1 million active users of business, not individuals. It was a metric that even Microsoft was being transparent about when reporting their numbers.

So how it is that no one has managed to oust his throne AWS IaaS? Then we offer a comparative analysis with the support of Gartner, and five case studies taken from AWS and Unicorn Fortune 500 companies.

Compare Magic Quadrant

Each year, Gartner published an analysis of positioning for players competing in the major markets of technology, called Magic Quadrant Gartner.

Using the graphical support and a set of evaluation criteria a Magic Quadrant lets you quickly determine how technology providers execute their visions and how they are performing against the notice Gartner.

In all types of Magic Quadrant, two axes representing the evaluation criteria Gartner - ability to execute and completeness of vision - provide four dimensions to map players competing: Leaders, Visionaries, Niche Players and challengers.

Leaders perform well against their current vision and are in good position for tomorrow, and Visionaries understand where the market is going or have a vision to change the rules of the market, but do not run not as good as the leaders.

Challengers execute well today or can dominate much, but do not show an understanding of market direction, while niche players focused successfully on a small segment and do not innovate or other overcome.

So what Gartner see that the forces of Amazon?
  • Diversified customer base
  • The widest range of use cases (native cloud applications hosting e-commerce, general business applications, Business applications, development environments and batch computing) → chosen primarily for strategic 
  • Large ecosystem of technology partners, including ISVs integrating their solutions with 
  • Extensive network of partners that offer the experience of application development, managed services and professional services such as data migration 
  • Richer range of IaaS and platform as a service (PaaS) 
  • Offers fast services and expansion of class solutions

However, Gartner also offered some drawbacks to offer Amazon: 

  • Perhaps a provider for complex 
  • The separate charges for additional items that are sometimes included in competing 
  • Support levels based on customers based on purchases of support chosen, rather than "relationship" or based waist and spending 
  • Broad capabilities means services that attract less interest customers do not get the same level of investment sought by 
  • New skills are often competing with products and services from partners AWS potentially leading to conflict ecosystem
Amazon has been in longer than the other two giants Microsoft and Google, which gave them a first-mover advantage in what Amazon calls the virtuous circle cloud business: pricing based on the value → more customers use plus more → → → → economies of scale infrastructure to reduce infrastructure costs → continuous innovation value / return.

Here's why large companies listed on the Fortune 500 list and Unicorn have chosen to use the AWS cloud to meet your needs.
