Finding and Fixing Inefficient Mainframe Integrations

•

0 likes•107 views

The document discusses identifying and fixing inefficient mainframe integrations. It describes how HostBridge has 20 years of experience helping customers with CICS integration issues. Inefficient integrations can be identified by long wait times for mainframe data, inability to scale transactions despite capacity upgrades, and service denials during peaks. The top causes of poor performance are screen scraping interfaces, implementation-based APIs, and external orchestration of mainframe requests. HostBridge's HTAC tool can help identify which integrations overconsume resources so they can be evaluated and the most effective mitigation path chosen, such as application modernization, process changes, architecture optimization, or z/OS tuning.

Top 3 Causes for Poor Integration Performance

1
Screen scraping /
terminal emulation
based interfaces
2
Implementation
based API
integration
3
External orchestration
of mainframe requests

Typical situations What we are able to identify and evaluate
Copyright © 2021 HostBridge Technology www.hostbridge.com
HATS or HATS-like solutions typically run many transactions unrelated to the
business/processing requirement.
Screen Scraping
Gateways
Screen Scraping
Clients/Macros
External
Orchestration
Screen-scraping macros and scripts can create a DOS-like attack on mainframe
apps and overconsume capacity for superficial application steps.
Orchestrating “fine-grained” apps/data from OUTSIDE the mainframe drives UP
mainframe resource utilization.
Technology-Based
APIs
APIs that expose implementation details create dependencies that inhibit
modernization objectives - and increases mainframe request volumes.

Why Use Low-Code Software for Your BSS?

Beesion

Explains why telecom companies should consider low-code software to supplement or replace their Business Support Systems (BSS) software. While there are many reasons, low-code software is quicker to change, deploy and enhance than traditional development. It also has lower TCO and enhances ROI. Plus it enables business users and IT to collaborate easily, so last-minute requirements or changes are no problem.

The Future of Mainframe Data is in the Cloud

Precisely

As organizations make the move to cloud platforms to support modern analytics and applications, they often need to move more than their on-premises data warehouses and lakes. Organizations often have legacy mainframe systems that run their mission-critical and revenue-generating applications, and that should be included in modern cloud projects. Yet it can be difficult to replicate mainframe data onto cloud platforms to make it a part of your data-driven initiatives, due to the data’s complex format. When moving data to the cloud it needs to maintain accuracy, consistency, and context to be considered trusted data. At the same time, the data needs to be available in real time to cloud-based data management and analytics applications. Join this session for a discussion with experts from Precisely and AWS about how to bring your data to applications and services on the cloud. Topics include: The importance of mainframe data for organizationsHow to migrate/replicate mainframe data to cloud platformsHow to ensure trusted data on cloud platforms

Cloud computing in practice

Andrzej Osmak

This document discusses how digital transformations require hybrid cloud solutions. It provides examples of how hybrid cloud can provide cost savings and new revenue opportunities for businesses. The key aspects of developing a hybrid cloud strategy are preparing workloads for migration, developing a business case, determining deployment options, and creating a cloud strategy and roadmap. Security, privacy, and compliance also must be addressed when planning a move to hybrid cloud.

Principled Technologies

A cluster of these servers ran a mix of applications with up to 27 percent better application performance than a previous-generation cluster, which could allow companies to do a given amount of work with fewer servers Conclusion As you do your best to balance timing, budget, IT resources, and your current and anticipated server needs, consider how opting for newer servers could help your business. As our testing showed, there are clear benefits to choosing servers that support such workload requirements as keeping databases running at a quick pace and delivering speedy hosting for your business’s website. Plus, a solution that offers the capacity and software features to perform well while natively supporting Kubernetes containers could add value in terms of setup, flexibility, scalability, and cost-effectiveness. And you can achieve all of this and possibly reduce OPEX in the process. In our testing with a mixed workload that reflects some of the needs common to small and medium businesses, a cluster of 16G Dell PowerEdge R7615 single-socket servers powered by 4th Gen AMD EPYC processors outperformed a cluster of previous-generation 15G Dell PowerEdge R7515 servers, with improvements of up to 27 percent and latency reduction of up to 50 percent. These results show that upgrading to the new Dell solution can be a smart step toward meeting the needs of your users now and in the years to come.

Performance And Scale In Cloud Computing 1

Scott Herson

This document discusses performance and scalability in cloud computing. It notes that poor application performance can negatively impact businesses by reducing customer retention, employee productivity and revenue. When moving applications to the cloud, businesses must ensure performance is optimized. To address performance issues, companies should first isolate non-cloud factors like network access speed and then test application performance on the cloud platform to identify any differences from the data center. Optimizing applications for the cloud architecture is important. The document also discusses various approaches to scalability in cloud environments and how Joyent offers solutions to aid application performance and scalability.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️

Łukasz Chruściel

No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception. In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed. We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
