According to an informal survey on a virtualization-specific Web site, consisting mostly of IT pros and executives familiar with cloud platforms, visitors are using Microsoft Azure almost as much as Amazon Web Services (AWS).
The Virtualization Practice, which claims to provide “Virtualization and Cloud Computing News, Resources, and Analysis,” conducted this survey. It asked one question: “Which Clouds do you use?”
The answer was that 39 percent of respondents use AWS; 35 percent are using Azure; 27 percent employ VMware vCloud (a private cloud); and 18 percent currently aren’t using any form of Infrastructure-as-a-Service (IaaS) cloud. “It’s interesting to see the percentage of people who don’t use IaaS-based cloud services. The survey’s author Edward Haletky said that Amazon and Azure rank higher than all private clouds.
It was also interesting to see that 36% of respondents use more than one cloud. Sixteen percent use at least two clouds, while 20 percent use three or more.
Haletky summarized the numbers as follows: “What we found is that the type and type of cloud that we use really matters and that we aren’t hypervisor-agnostic yet.” He also mentioned that only a few were using OpenStack, an open source platform for private cloud primarily.
Haletky declined to provide the exact number of poll respondents in an e-mail exchange but he believes that the results are valid. He said, “It’s not scientific, but it’s pretty accurate considering our readership.”
Haletky stated that the survey revealed several attitudes towards cloud computing. One is that Azure is invading on AWS more than expected, which may explain why Amazon is updating AWS so frequently. Another reason Azure is so successful is Microsoft’s position within the datacenter. Haletky stated that Azure’s success is due to two factors. First, Microsoft products need a cloud that can run them well. Second, Azure does.NET very well indeed. Active Directory is [in my humble opinion] the secret sauce. Azure is a great place to host Windows workloads.
Another surprise was the fact that the brand of cloud selected was less important than its intended purpose. “The cloud of clouds was more surprising than standardization. Haletky stated that function is more important than form. He concluded that clouds were selected for their unique features and not because they had to be associated with a particular vendor.
Haletky also found positive news for VMware in the survey results. He said that the hypervisor may still be relevant for some workloads, based on the numbers for VMware Cloud Air. This is an avenue through which VMware private clouds can easily grow beyond their datacenter boundaries.
According to data released by Synergy research Group, cloud spending exploded by $2.8 billion during the fourth quarter 2019. This is the largest sequential-quarter growth in cloud market history.
Amazon Web Services (AWS) was the leader of the charge. Although AWS’ year-over year growth has been slowing (in its most recent financial reports, AWS recorded a 34 percent decrease in its year-over year growth), it has maintained pace with the overall cloud market which Synergy estimates has grown 37 percent year-over year.
AWS’s closest competitors outpaced the market in Q4. Despite slow growth, AWS’ cloud dominance is unaffected. According to Synergy, it currently holds 33 percent of global market.
Microsoft Azure, its closest competitor, reported a 62 per cent year-over-year rise, giving it 18% of the market — almost three percentage points more than the year-ago period.
The top five market share leaders are Google, Alibaba, Tencent. “Google, Alibaba, and Tencent are significantly outpacing overall market growth. They are also gaining market share. Synergy stated that revenues increased by at least 50% year-over-year for all three companies. The five market leaders together account for more than 75 percent of total market.
Synergy reported that the total cloud market revenues for 2019 reached $96 billion. Q4 brought in $27 billion.
John Dinsdale (chief analyst at Synergy), stated that “the year ended with a bang” because Amazon and Microsoft both posted big sequential gains on cloud revenues. “The 2019 market was more than twice as large as the 2017 market, thanks to strong growth from other cloud providers and these market leaders,” said John Dinsdale, chief analyst at Synergy. We will continue to witness strong growth due to secular trends in this market.
Amazon Web Services Inc. (AWS), has made it generally available an in-memory cache that increases the performance of Amazon DynamoDB, its NoSQL database service.
Amazon DynamoDB Accelerator (DAX), which was announced in April preview, promises a 10-fold performance improvement in DynamoDB queries.
AWS states that DAX does all of the heavy lifting to add in-memory speed to DynamoDB tables without you having to manage cache invalidation or data population. “Now you can focus on building great apps for your customers and not worrying about performance at scale.”
Yesterday’s blog post by Jeff Barr, AWS spokesperson, stated that the company used the preview period for fine-tuning the service. The service’s reach has been extended to additional AWS Regions, to increase the total to five.
The number of SDKs that developers can use DAX has not been expanded. Barr stated that Java’s DAX SDK is the only one currently available. However, AWS is working on other SDKs.
“DAX returns cached responses in microseconds, making it a great fit for eventually-consistent read-intensive workloads,” Barr said. “DAX supports DynamoDB API and is seamless and simple to use. You can simply create your DAX cluster as a managed service and use it to target your existing reads or writes. You don’t need to worry about cluster maintenance, patching, replication, fault management, or cluster maintenance.
Werner Vogels, the company’s chief technology officer, wrote a detailed post yesterday on his blog “All Things Distributed”, giving a glimpse into the history and technical details of DAX. He said that developers only need to point an application to a DAX Endpoint with three lines of Java code.
Vogels stated that DAX is a fully managed caching system that is API-compatible to DynamoDB. This means that developers don’t need to rewrite DynamoDB applications to use DAX. Instead, you can point your existing Java application to a DAX endpoint using the DAXSDK for Java. DAX takes care of the rest.
As referenced on the DynamoDB pricing page, users pay for the DAX add-on service on a per-node-hour-consumed model, starting at $0.269 per hour in the US East (Northern Virginia) and US West (Oregon) regions — other regions are slightly more.
You can find more information in the DAX documentation.
According to new research from SlashData, Amazon Web Services (AWS), is the most popular choice among developers in the cloud-native or serverless computing space.
The Developer Economics report by the company, “The State of Cloud Native Development”, was done for the Cloud Native Computing Foundation (CNCF), which is a Linux Foundation project. The report, which was based on data from a larger survey that was conducted in the second quarter last year, was released just this month.
The report found that AWS, the cloud kingpin, is No. AWS Lambda is the market leader in serverless (51 percent of serverless customers use AWS Lambda), followed closely by Google Cloud Functions, Azure Functions, and Google Cloud Functions.
AWS was also a popular choice for other cloud-native development scenarios. According to the report, cloud-native developers are significantly more likely than others to use AWS for their private cloud vendor. 60% of Cloud-Native developers use AWS as their private Cloud vendor.
Furthermore, 68 percent of developers who use containers-as-a-service but not the Kubernetes container orchestration tool use either Amazon Elastic Container Service (ECS) or Amazon Managed Kubernetes Service (EKS). According to the report, “Presumably these are developers who use the old ECS that isn’t built on Kubernetes.” 25 percent use Azure Container Service, while 14 percent use Docker Swarm.
CNCF however, compared this finding to its own survey. CNCF, however, stated that the CNCF report found that Amazon EKS was the most popular tool to manage containers at almost 30 percent.
CNCF found that public cloud was the most preferred datacenter approach. 62 percent of respondents named it, while 45 percent indicated they were using private clouds/on-premise. It was a new answer for 2019, but 38 percent of respondents chose hybrid, which indicates that it is a popular approach.
CNCF provided a link to the PDF report, which contains more information and complete methodology.
Amazon Web Services Inc. (AWS), is entering the digital Web site security certificate market. Amazon Web Services Inc. (AWS) has launched a new initiative that simplifies the process of using Secure Sockets Layer/Transport Layer Security certificates (SSL/TLS), which provide authentication and encryption services.
The company has launched the AWS Certificate Manager (ACM) to streamline and automate the complicated tasks associated with SSL/TLS certificate management. In a blog post last Wednesday, Jeff Barr, an executive at AWS, stated that ACM handles the complexity of provisioning and renewing digital certificates.
SSL/TLS certificates are a guarantee of Web site security. This is indicated by the little green padlock symbol that appears before the “https ://”” part of Web site URLs. It certifies that the site’s content comes from the right source.
According to the ACM site, SSL and its successor TLS are industry-standard protocols for encrypting network communications. They also establish the identity of Web sites over Internet. SSL/TLS provides encryption of sensitive data in transit and authentication using SSL/TLS certificate to establish your site’s identity and secure connections between browsers, applications and your site. AWS Certificate Manager makes it easy to create and manage SSL/TLS certificates.
AWS cloud users will now be able to use the new service for free with their Amazon CloudFront distributions and Elastic Load Balancers. AWS states that Elastic Load Balancing automatically distributes incoming traffic across multiple Amazon EC2 instances. Amazon CloudFront, on the other hand, is a content delivery Web-service that allows for quick and easy distribution of content.
Barr stated that SSL/TLS is essential for sensitive data being moved back and forth. SSL/TLS is used extensively by sites that must comply with compliance requirements such as FedRAMP, PCI-DSS, and HIPAA.
The ACM is currently only available in the US East (Northern Virginia), with more regional availability in the future.
Amazon Web Services Inc. (AWS), took another step to make it easier to develop mobile and Web apps in cloud using its AppSync API.
The company launched an API Builder that can be used with its AppSync service to create data-driven apps with offline and real-time capabilities.
AppSync has one restriction: developers must be familiar with GraphQL. This open-source data query and manipulation language is combined with a runtime to handle queries with existing data. It was originally created by Facebook.
AWS published the “no code” GraphQL API builders in July in an effort to “release” this requirement. Now it has taken another step in simplifying the process.
“With today’s launch, it is even easier to create a powerful serverless API for mobile and web apps without any prior knowledge or GraphQL,” the company stated in a Sept. 21 blog posting.
The guided API builder allows users to create a data model that corresponds to their application’s business logic using a web form. It automatically creates the GraphQL schema and Amazon DynamoDB table and resolvers for your app backend. AWS AppSync can also be accessed from your DynamoDB table. This will allow you to create a data model that corresponds to your existing data.
AWS also published a tutorial on how to use the guided API builder.
Amazon Web Services Inc. (AWS), announced today a new machine-learning service at its summit, promising to simplify technology.
Machine learning (ML), which uses an algorithmic approach for analyzing historical data, is used to create predictive models and guide decision making.
These models can be used to filter spam, detect fraud, personalize content, retain customers, and market among other uses.
AWS announced Amazon Machine Learning. It stated that it wants to make the technology more accessible to the general public, much in the same way Big Data is becoming “democratized” through simplified usage so that anyone can use the technology, even non-specialists.
AWS stated that “Until now, very few developers were able to create applications with machine-learning capabilities because doing so required expertise data analysis, statistics, and machine learning.” Machine learning is a tedious, repetitive and error-prone process that involves manual tasks. These include computing summary statistics, performing data analyses, performing data analysis, and using machine learning algorithms to train models based on data. The model can then be evaluated and tuned, and then the model can be used to generate predictions. Amazon Machine Learning makes machine-learning accessible to all software developers. It abstracts away the complexity and automates these steps.
AWS stated that the fully managed and highly scalable service is built on the same technology internal developers use for more than 50 billion predictions per day.
Developers can access the service’s APIs (or its AWS Management console) and use visualization tools and wizards, to create ML models that work with data from stores like Amazon Simple Storage Service (Amazon S3) or Amazon Redshift (Amazon RDS).
“Amazon has a long history in machine learning. It powers product recommendations customers get on Amazon.com. It is also what makes Amazon Echo respond to your voice. It is also what allows us unload entire trucks of products and make them available for sale in as little as 30 seconds,” stated Jeff Bilger, a company executive. “We recognized early on that machine learning was only possible if it was made available to all Amazon developers. Amazon Machine Learning is the culmination of all the lessons we’ve learned while enabling thousands upon thousands of Amazon developers to quickly create models, test, and scale to power planet-scale predictive apps.
AWS stated that the ML service is available as a pay-as you-go service. This allows developers to start small projects and then scale up as required. Pricing information is available based on the different fees for data analysis, model building, and storage.
Catch-all Path Variables — Rather than specifying individual paths or behaviors for groups of requests falling within a common path (such /store/), it is now possible to specify a catch all route that intercepts all requests and routes them to the exact same function. For example a single greedy path (/store/proxy+) will intercept requests made to /store/list-products, /store/add-product and /store/delete-product.
Any Method — Instead of specifying different behaviors for each HTTP method (GET/POST/PUT, etc.), you can now use catch-all ANY method for the same integration behavior for all requests.
Lambda Function Integration — This new default mapping template will send all of your request to your Lambda functions and then convert the return value into an HTTP reply.
HTTP Endpoint Integration — A new default mapping template that will pass the entire request to your HTTP endpoint, and then return the response with no modifications. This allows API Gateway to be used as an HTTP proxy without any setup.
Barr also provided a glossary of terms for the uninitiated to help them understand the new features.
Endpoint — A URL provided by API Gateway that responds to HTTP requests. These requests use HTTP methods like GET, PUT, and POST.
Resource — A named entity that exists symbolically within an endpoint. Referred to as a hierarchical path.
Behavior — The action your code will take to respond to an HTTP request for a resource using an HTTP method.
Integration — The API Gateway mapping between the endpoint, resource, and HTTP method to the actual behavior and back.
Pay-as-you go customers can access the new features at no additional cost. Learn more about the Amazon API Gateway Developer Guide for developers.
