The document provides an introduction to cloud computing concepts from Infrastructure as a Service (IaaS) to Platform as a Service (PaaS) to Software as a Service (SaaS) to Database as a Service (DBaaS). It discusses different cloud models including private, public, multi-cloud and hybrid clouds. It also covers cloud native technologies like Kubernetes and microservices. The document cautions that while cloud promises flexibility and agility, the realities of cloud adoption require assessing one's specific business needs and whether a cloud provider can truly deliver the desired advantages. It promotes BigAnimal as a fully managed PostgreSQL database service in the cloud to help enterprises with their cloud journeys.

Microcontainers and Tools for Hardcore Container Debugging

Oracle Developers

Entergy, a large utility company headquartered in New Orleans, LA has launched an initiative to modernize their application infrastructure. During the initial analysis, Entergy recognized the existing legacy infrastructure’s lack of compatibility with more recent operating systems would stand in the way of progress. As a result, containerization was fast-tracked as the solution that can help them with the various tenants of their strategy: hyperconvergence, SaaS (ServiceNow), and workload portability. Docker Enterprise proved to be the right solution to migrate roughly 850 legacy applications from Windows Server 2003 and 2008 to Windows Server 2016 quickly, securely and economically. Entergy IT has now delivered the ability for the business to run applications on-premise, in the cloud, and future-proofed the applications for migration to new versions of Windows Server. In this session, Entergy will talk about how they are modernizing their infrastructure to become more agile, secure, and enable workload portability.

Very few trends in IT have generated as much buzz as cloud computing. This session will cut through the hype and quickly clarify the ontology for cloud computing. The bulk of the conversation will focus on the open source software that can be used to build compute clouds (infrastructure-as-a-service) and the complimentary open source management tools that can be combined to automate the management of cloud computing environments. The session will appeal to anyone who has a good grasp of traditional data center infrastructure but is struggling with the benefits and migration path to a cloud computing environment. Systems administrators and IT generalists will leave the discussion with a general overview of the options at their disposal to effectively build and manage their own cloud computing environments using free and open source software.

How to build a highly available PostgreSQL Cluster using EDB Failover Manager? Database downtime can cost your business significant revenue. And while PostgreSQL is incredibly stable, it does not identify a database failure or automatically switches traffic to a standby database. In such a scenario, EDB Failover Manager (EFM) can be at the forefront of automatically detecting master database failures and promoting the most up-to-date standby database to take over. Register for this free webinar and learn how EDB Failover Manager helps you build a highly available PostgreSQL Cluster for overall business continuity.

Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional.

ADR, or Architecture Decision Record, is a valuable tool in software development for several reasons. It provides a centralized location for documenting and tracking architectural decisions, aiding both current and future team members. ADRs enhance communication among team members by documenting the rationale behind architectural decisions, especially beneficial during onboarding of new team members or when revisiting decisions. They serve as a knowledge base, enabling teams to learn from past decisions and refine their decision-making process. Additionally, ADRs contribute to transparency by helping stakeholders understand the reasons behind specific architectural choices. As with any other tool or process, introducing them into an organization can face several obstacles, and overcoming these challenges is crucial for successful implementation. In this talk I go through some common problems and our way of solving them.

Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want.

Modeling languages are generally applied for developing systems and software – both internally, with domain-specific languages, and with standardized languages targeting a general purpose and a wide audience. Way too often these languages are weakly created and defined leading to poor quality: Language definitions tend to contain errors and inconsistencies; notations do not recognize the communication and problem-solving needs of humans; standardization organizations push exchange formats that do not fully work and offer certificates that do not measure mastery of the language. We describe common problems in language development and point them out with examples from known cases. To overcome these problems, we suggest several solutions to improve language development, including using modeling languages specifically designed to define modeling languages, continuous testing and prototyping, and keeping language users in the loop.
