Feed: AWS for SAP. Author: Ferry Mulyadi. Introduction Cloud Security is job zero at AWS. We have a Shared Responsibility Model where customer assumes responsibility and management of the guest operating system (including updates and security patches), other associated application software as well as the configuration of the AWS services. A common question that new customers ask is how they can secure their mission critical SAP workloads. AWS has recently introduced AWS Well-Architected Framework for SAP (SAP Lens), which describes the best practices when implementing security control based on your requirement. One of the best practice is to ensure that ... Read More

Feed: AWS Architecture Blog. Architecting workloads to achieve your resiliency targets can be a balancing act. Firms designing for resilience on cloud often need to evaluate multiple factors before they can decide the most optimal architecture for their workloads. Example Corp has multiple applications with varying criticality, and each of their applications have different needs in terms of resiliency, complexity, and cost. They have many choices to architect their workloads for resiliency and cost, but which option suits their needs best? Will they have to make any sacrifices to implement one over another? How and why should they choose one ... Read More

Feed: Planet MySQL; Author: Daniel Nichter; Chapter 4 Apr 17, 2022 Access patterns intrigue me because it seems that everyone knows what they are and talks about them, but there’s also very little written about them—in MySQL literature, at least. That’s why I set out to enumerate a list of access patterns (specific to MySQL). Since there’s no apparent standard for access patterns, I cannot say how my list measures up, but after spending most my career with MySQL, I know this: it is necessary to consider these access patterns when evaluating and improving MySQL performance. Simply put: you cannot ... Read More

Feed: Matillion. Author: Julie Polito; This is the final article in a five-part series on data integration. The series covers the following foundational topics:Data Has State – Data Functions and Design Patterns – data processing functional design patterns, and the development lifecycle Statefulness is unique to software that integrates data. It means that data processing software can never be fully understood in isolation. What happens next always depends very much on what happened before. This has a big impact on the ability to iterate data processing solutions quickly and reliably.The goal of data integration is to combine data in a ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Ameer Hakme. Whether you are just starting with your Internet of Things (IoT) journey, or already have millions of connected IoT devices, you might be looking for ways to maximize the value extracted from your IoT data. IoT devices data can contain a wealth of information within its reported telemetry data, metadata, state, and commands and responses. However, having the right reporting and visualization solution is key to gain insights needed to maximize your operational efficiency and deliver business outcomes. No one solution can fit every use-case, hence frameworks ... Read More

Feed: AWS Public Sector Blog. Author: Rafael Monge Vargas. Though it accounts for only 0.03% of the Earth’s surface, Costa Rica is home to about 6% of the world’s biodiversity. Leveraging Costa Rica’s rich biodiversity and advancements in ecosystem modeling, leaders in sustainability are making geospatial data and analysis of Costa Rican landscapes publicly accessible. The data and analysis help people understand how different species influence their ecosystems, while also informing important policy decisions that support the natural world. As part of the Amazon Sustainability Data Initiative (ASDI)—a program that seeks to accelerate sustainability research and innovation by minimizing the ... Read More

Feed: R-bloggers. Author: R-bloggers | A Random Walk. Turing patterns are a type of reaction-diffusion systems that have attracted much interest as a basic model for the formation of patterns in nature, such as stripes, spots and spirals. The behavior of such diffusion systems was studied by Alan Turing in his classical paper (Turing 1952) and a few decades later re-discovered by (Gierer and Meinhardt 1972), which lead to a more widespread use of the systems in biology as well as other fields. Turing-like patterns involve activating and inhibiting substances that diffuse through a tissue. If the activator substance diffuses ... Read More

Feed: AWS Architecture Blog. Many organizations with large ecommerce presences have procedures to detect major anomalies in their user traffic. Often, these processes use static alerts or manual monitoring. However, the ability to detect minor anomalies in traffic patterns near real-time can be challenging. Early detection of these minor anomalies in ecommerce traffic (such as website page visits and order completions) helps organizations take corrective actions to address issues. This decreases negative impacts to business key performance indicators (KPIs). In this blog post, we will demonstrate an artificial intelligence/machine learning (AI/ML) solution using AWS services. We’ll show how Amazon Kinesis ... Read More

Feed: Redis. Author: Redis Growth Team. Citi Bike remains the nation’s favorite bike share program. With over 20,000 bikes scattered across Manhattan, Brooklyn, Queens, and the Bronx, getting from A to B has never been easier. It’s cheap, it’s convenient and it’s green. And most notably, it’s popular. Thanks to this Launchpad App, you’re now able to discover how many bikes are used at different times, throughout each day, in different neighborhoods across the city.  Despite New York offering other modes of transport, those who are committed to a healthier and greener way of living can plan their trips in ...

Feed: AWS Architecture Blog. Event driven programs use events to initiate succeeding steps in a process. For example, the completion of an upload job may then initiate an image processing job. This allows developers to create complex architectures by using the principle of decoupling. Decoupling is preferable for many workflows, as it allows each component to perform its tasks independently, which improves efficiency. Examples are ecommerce order processing, image processing, and other long running batch jobs. Amazon Simple Storage Service (S3) is an object-based storage solution from Amazon Web Services (AWS) that allows you to store and retrieve any amount ... Read More
