Transforming Legacy Applications Into Dynamically Scalable Web Services
The tools and technologies used to power the modern data center are evolving at a pace faster than most companies can keep up. Aging web services built on LAMP, WAMP, or ASP cannot readily take advantage of the latest in scalable web platforms and technologies. In this presentation, we will discuss what factors must be considered in order for your aging web service to take advantage of technologies such as Apache Mesos, Marathon, Docker, Apache Kafka, and more.
This talk is intended for software developers, operations, and IT managers who are looking to modernize existing privately-hosted web applications. We will look at the transformation of the data center from a high-level perspective, examining before and after topology examples using Key Performance Indicators and Key Performance Metrics to show how levering modern design principles can both improve application performance and reduce operational costs. Next we will look at some example applications and show what needs to be done from both the software development and infrastructure perspectives to successfully accomplish the transformation.
Monitoring microservices platform
In this talk we explore some of the tools we built at Hailo to monitor our microservices platform. By using a combination of instrumentation, in-depth service monitoring, request tracing, event correlation and automation frameworks we manage to present a holistic view of our infrastructure.

Hosting rails apps
The document discusses different options for hosting Rails applications, including shared hosting, VPS, and dedicated servers. Shared hosting is the cheapest option but has limitations in terms of resources and customization. VPS hosting provides more control over the server but still has resource constraints. Dedicated servers are fully customizable but the most expensive. The document also outlines various considerations for setting up a Rails application hosting environment, such as hardware, software, databases, deployment, backups and more. Popular shared hosting providers, VPS providers, and PaaS options for Rails apps are also listed.
Service fabric overview
The document compares the monolithic and microservices application approaches. It notes that the microservices approach separates functionality into independent services that can each be scaled independently, while the monolithic approach has all functionality within a single process. It also discusses how microservices use various technologies and databases, while monolithics typically use a single database.
The Java Microservice Library
The Java microservice lib. QBit is a reactive programming lib for building microservices - JSON, HTTP, WebSocket, and REST. QBit uses reactive programming to build elastic REST, and WebSockets based cloud friendly, web services. SOA evolved for mobile and cloud. QBit is a Java first programming model. It uses common Java idioms to do reactive programming.
It focuses on Java 8. It is one of the few of a crowded field of reactive programming libs/frameworks that focuses on Java 8. It is not a lib written in XYZ that has a few Java examples to mark a check off list. It is written in Java and focuses on Java reactive programming using active objects architecture which is a focus on OOP reactive programming with lambdas and is not a pure functional play. It is a Java 8 play on reactive programming.
Services can be stateful, which fits the micro service architecture well. Services will typically own or lease the data instead of using a cache.
CPU Sharded services, each service does a portion of the workload in its own thread to maximize core utilization.
The idea here is you have a large mass of data that you need to do calculations on. You can keep the data in memory (fault it in or just keep in the largest part of the histogram in memory not the long tail). You shard on an argument to the service methods. (This was how I wrote some personalization engine in the recent past).
Worker Pool service, these are for IO where you have to talk to an IO service that is not async (database usually or legacy integration) or even if you just have to do a lot of IO. These services are semi-stateless. They may manage conversational state of many requests but it is transient.
ServiceQueue wraps a Java object and forces methods calls, responses and events to go through high-speed, batching queues.
ServiceBundle uses a collection of ServiceQueues.
ServiceServer uses a ServiceBundle and exposes it to REST/JSON and WebSocket/JSON.
Events are integrated into the system. You can register for an event using an annotation @EventChannel, or you can implement the event channel interface. Event Bus can be replicated. Event busses can be clustered (optional library). There is not one event bus. You can create as many as you like. Currently the event bus works over WebSocket/JSON. You could receive events from non-Java applications.

Multi-Cloud Global Server Load Balancing (GSLB)
Watch on-demand https://info.avinetworks.com/webinars/global-server-load-balancing
GSLB has been traditionally deployed across multi-site data centers for disaster recovery and faster app response time. Increasingly, GSLB is applied across on-prem data centers and public clouds to better serve geo-distributed users. However cloud load balancing is lacking in terms of enterprise-class GSLB support. With distributed containerized applications and microservices deployed in Kubernetes clusters, visibility and health monitoring becomes ever more critical.

COMMENT LE MOBILE IMPACTE LE MARCHÉ DIGITAL DU TOURISME SELON UNE ÉTUDE CRITEO ET PHOCUSWRIGHT
Le PC représente encore environ les deux tiers des transactions en ligne de tourisme (de 64% à 71% en fonction des 8 pays étudiés). Le mobile progresse et atteint 20% (smartphones + tablettes) d’utilisation en France par exemple. Cette proportion monte à 87% pour la Chine.
La réservation sur mobile est à un stade de développement dans la plupart des pays étudiés. En France, seuls 6% des vols sont réservés sur mobile, contre 31% pour la Chine.Si l’aérien reste le point fort du PC (94% des réservations en France), le parcours d’achat mobile bénéficie principalement aux intermédiaires de voyage en ligne. Ainsi, pour acheter un billet d'avion, les mobinautes français passent d’abord par des intermédiaires (14%) puis par le vendeur direct (9%). Pour un achat hôtelier, ils sont 5 fois plus nombreux à passer par des intermédiaires (10%) que par des vendeurs directs (2%).

The document discusses the future of mobile roaming as disruptions are occurring in the roaming market. Historically, roaming charges have been very profitable for mobile operators, but high prices have discouraged customers from using their phones when traveling abroad. As a result, it is estimated that 70-80% of roamers do not use data services while traveling (silent roaming), representing a large untapped market opportunity for operators. Regulatory interventions have also weakened operators' control over pricing. The removal of roaming fees in Europe by 2015 will further impact operators who stand to lose around €1.65 billion annually from lost roaming revenue. Operators need to introduce new services and packages to take advantage of increased data usage from

Carrier-Class Environments for NFV Lifecycle Management- Overture & Wind Rive...
This Intel Network Builders Webinar is on Carrier-class environments for NFV lifecycle management. Communications service providers see the strong business upside from deploying NFV-based services. NFV promises to lower costs, simplify network operations, and usher in a new era of rapid service innovation. However, there are still concerns about running mission-critical, revenue- generating network functions as software applications on general purpose compute platforms rather than purpose-built appliances.
Intel, Wind River and Overture explore what is required to create a carrier grade, high-performance environment for hosting virtual network functions (VNFs).
Learn how to:
• Create a high-performance, high reliability NFV infrastructure
• Identify essential attributes needed for carrier-class management and orchestration
• Optimize the placement of VNFs and the benefits of distributed and centralized models • Support the complete service life cycle in a VNF-agnostic service environment
The Price War of Telecommunication Giants in India
This document provides an overview of the price war between major telecommunication companies in India. It discusses the growth of the telecom industry in India in recent decades, with subscriber numbers increasing rapidly. This substantial growth in demand has led to intense competition between companies like Bharti Airtel, Vodafone, Idea Cellular, and Reliance as they try to acquire more subscribers by continually lowering prices for services like calls and internet access, resulting in a price war. The document analyzes how this price war impacts both customers, who benefit from lower prices, and the companies' profits.

European M Pos Providers
As economic conditions improve across Europe, micro, small, and medium enterprises (MSMEs) are starting to rebound. With consumers’ payment card use growing, accommodating their shifting payment preferences is increasingly valuable to merchants. As a result, the European merchant acquiring field has seen a surge in providers, old and new, offering mobile point-of-sale (m-POS) devices and attempting to differentiate themselves.
The diversity of acquirers providing m-POS devices stems from the devices’ potential to generate new revenue streams, bolster acquiring relationships, and enhance the electronic payment experience for both consumers and retailers. To date, the devices represent only a small portion of the installed POS terminal base, but signs point to their rapidly becoming the preferred checkout instrument of retailers of all sizes due to the cost and efficiency savings of these handheld terminals.

Carrier-grade-virtual-platform-use-case
Virtual routing platforms allow carriers to take advantage of virtualization benefits while supporting SDN and NFV initiatives. They aim to provide carrier-grade routing functions with performance comparable to physical routers, using the same management systems and consistent behaviors. Virtual platforms are well-suited for new applications where physical routers cannot meet needs, and allow flexible, on-demand scaling and lower costs than physical routers. Both physical and virtual platforms have strengths and can form blended networks, with services placed based on requirements. Virtual platforms open new approaches to network design and service delivery.

Software defined network-- SDN
SDN most commonly means that networks are controlled by software applications and SDN controllers rather than the traditional network management consoles and commands that required a lot of administrative overhead and could be tedious to manage on a large scale
“What is SDN? The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.”
TIA sdn transport_2_shukla_final
The document discusses the promise of SDN for transport networks. It notes changing business and usage models are driving the need for more elastic, on-demand networks. SDN can help by providing programmable control of optical networks through standardized interfaces. The OIF and ONF conducted a global demo of transport SDN using an application for cloud bursting over optical networks. This identified gaps around multi-domain control and relationships between controllers and network management. Wider SDN deployment faces challenges around operational simplicity, scalability, security and continuous availability. Multiple SDOs are working on related standards but alignment is still needed.
Research Challenges and Opportunities in the Era of the Internet of Everythin...
Currently there is increasing interest in scientific research on network traffic management for advanced scenarios (e.g. Internet of Everything (IoE), Everything as a Service (XaaS), Smart Cities, and the like) and their respective demands for novel network services. Such networked applications bring massive amounts of traffic data to be processed in real-time, thus driving researchers to develop affordable yet efficient network management systems. In fact, new paradigms, services, and architectures, such as Network Virtualization (NV), Software-Defined Networking (SDN), Distributed Cloud Computing, Network Functions Virtualization (NFV), Service Function Chaining (SFC), etc, will require robust and dynamic capabilities to support a myriad of possibilities for applications from the IoE and XaaS concepts. For example, there is a need for an in-depth understanding of the composition and the dynamics of Internet traffic to perform accurate capacity planning, deploy efficient management policies and pricing strategies, assess protocol performance, and detect abnormalities in such scenarios. Research on measurement, modeling, and analysis of network traffic and infrastructure always face new challenges as new applications are continuously deployed.
In this talk, I will discuss the rise of IoE and XaaS as well as the demand for advanced networking services, paradigms, and architectures (e.g., SDN, NFV). I will give an overview of some challenges, opportunities, and directions in these research topics.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
