Oracle y Red Hat abanderan un nuevo estándar para la nube


Fuente: ComputerWorld España.

Con el nombre de CAMP, una serie de proveedores cloud liderados por Red Hat y Oracle han sentado las bases de un nuevo estándar que busca facilitar el uso y la gestión de las cargas de trabajo en entornos PaaS (Platform as a Service). 

La nube, cada vez más estandarizada. Esa es la tendencia que la industria parece estar impulsando en la actualidad y buena prueba de ello es que varios de los principales proveedores del sector han trabajado juntos para impulsar un nuevo estándar en entornos PaaS. 

Así, Oracle y Red Hat (junto a otras empresas de la talla de Rackspace, Huawei, Software AG o CloudSoft) han sentado las bases de un estándar para los comandos de control de las nubes PaaS, un hecho que permitirá migrar de forma fácil y sencilla las cargas de trabajo de un servicio a otro. 

Y es que en los últimos tiempos han proliferado las ofertas de servicios PaaS pero cada proveedor, como Elastic Compute Amazon Cloud (EC2) o Microsoft Azure, ofrecía su propia consola, incompatible con las restantes. Tal vez el mayor esfuerzo hasta ahora para normalizar las PaaS ha sido Eucalyptus, una plataforma cloud de código abierto que utiliza las API de Amazon. 

"El inicio y la detención de una aplicación realmente deberían ser estandarizados para que sea más fácil para los clientes gestionar sus aplicaciones en diferentes plataformas", afirma Jeff Mischkinsky, director senior de Oracle Fusion Middleware, quien ha tenido un papel fundamental en el desarrollo de la norma. 

La norma, recogida por la OASIS (Organización para el Desarrollo de Estándares de Información Estructurada), ha recibido las siglas de CAMP (Gestión en la nube de aplicaciones entre plataformas) y se compone de una API que coordina un conjunto de comandos para gestionar las cargas de trabajo de las PaaS. 

CAMP también incluye especificaciones sobre cómo empaquetar una carga de trabajo. "Definimos las necesidades básicas de todo el ciclo de vida de las aplicaciones", explica Mischkinsky. En futuras ediciones de la norma se abordarán nuevas funcionalidades, todas ellas encaminadas a facilitar la migración de las cargas de trabajo. 

Oracle: Leading with Linux, Then and Now

Oracle LinuxCon Presentation
Sourge: , linux.com

Adopting Linux as a platform has helped change Oracle over the past 15 years from a fragmented, decentralized behemoth to a sleek, consolidated service provider, said Senior VP and CIO Mark Sunday in Oracle’s LinuxCon keynote presentation Friday morning.

In exchange, Oracle also played a large role in shaping Linux, especially in the server space, said Wim Coekaerts, Oracle’s Senior Vice President of Linux and Virtualization Engineering, during the presentation.


Linux is the standard operating system for all of Oracle’s internal business systems and product development as well as the basis for the business services the company offers its customers, he said.

“Everything we do… is done leveraging Linux,” Sunday said.

On the product development side Oracle now has 40,000 environments all running on heavily virtualized Linux servers. This “Oracle farm” was the company’s first cloud deployment, allowing on-demand provisioning of resources that are scalable and widely available, Sunday said. The company offers those same resources to customers with managed hosting on Oracle products and a wide variety of software-as-a-service products.
Now the company is scaling up again and integrating Linux into the systems it builds for customers. The roughly 100 acquisitions Oracle has made over the past eight years have been aimed at gathering all of the components to make a complete integration possible, Sunday said. For example, companies no longer need to buy servers and storage networking then layer in a file system and a database. Oracle packages it into a single IT product.

A Stable Enterprise OS Evolves

Oracle contributions to the Linux kernel helped bring the operating system up to speed with other Unix-based systems in the early days. The company’s involvement eventually led to the “somewhat controversial” decision to become a Linux distribution vendor, providing support for the whole stack, said Coekaerts.

The next step in Oracle’s evolution with Linux was building an extensive testing system in 2008 and 2009, Coekaerts said.

“It’s not just about development when you produce a product,” he said. “Bug fixing and QA is the less cool part but a very critical part.”
In the past few years the development model for Linux has changed and the pace of releases has become very rapid. New features are available for customers as soon as they are added and users are increasingly defining the platform.

After kernel developer Greg Kroah-Hartman pushed legacy vendors to be more current, Oracle began providing a kernel to customers that is more mainline-based, within five to six months of the new releases, Coekaerts said.

“Linux has been very useful to us in getting new features into the hands of customers sooner,” Coekaerts said.

“If we’re closer to what Linus maintains we have new features sooner,” he said.

The challenge now lies in continuing to improve the operating system’s performance and reliability. The QA process will be critical to this, Coekaerts said, but not all developers have in-house access to a test suite like the larger distributions provide to their developers, he said.

“We need to have a test suite for the operating system that ships with the kernel source,” Coekaerts said. “It’s important to start building test suites for Linux features as the kernel develops.”

What is MySQL denormalization and should you be doing it?

Introduction

Originally, I was going to write an tutorial over MySQL Performance Tuning Tips & Tricks. I quickly realized that this tutorial would be a bullet list of Tips & Tricks, and thus would be too short and require users to go searching elsewhere for terms they did not understand, or would lose users because it would become far too long. Instead I decided to hash out a series of tutorials to publish individually. While none of these tutorials will build off of each other, some terms you learn in one may be referenced in others.

In this tutorial we will take a look at what Database Denormalization is and how it is different from Normalization. Many DBAs probably use the Normalization rules in designing databases, either because they have never heard of Denormalization or they do not fully understand it.

What is Normalization?

We will start off by looking at Database Normalization. The primary reason for this is because many people were taugh that they should always "Normalize" their databases. Normalized data means that fields and tables in a relational database have been organized to reduce redundancy and dependency by dividing up larger tables and linking them through the uses of Indexes. While this makes for a cleaner overall layout, and seems to make sense, it is not always the best course of action.

Why do people Normalize?

In my opinion, the answer to this question is because that is how they were taught. For some reason the most widely accepted method of teaching is the Normalized method described above. It seems to make sense to populate, modify and delete data in one table and have it propagate through the entire database through the use of defined relationships.

One example of where this would make sense would be a table called students. The denormalized layout for this table would have the following columns: student_id, student_name, student_email, student_address, course_number. In this example, a student could easily be enrolled in 10-15 different courses. If that students address changed for any reason, that would mean that a query would have to perform 10-15 updates on the address column for that student.

The normalized approach for the same example would have a students table (student_id, student_name, student_email, student_address) and a enrolled_courses table (enrolled_course_id, student_id, course_name, course_number). We might even take this one step further and move course_name and course_number to a table called courses (course_id, course_name, course_number). That would mean our new enrolled_courses table would look like: enrolled_course_id, course_id, student_id.

In the denormalized approach lets assume that it is a new semester and student A did not re-enroll for that semester because he needed planned to take a semester break. Since the semester has ended we would empty all the rows from the database since students will no longer be enrolled in those courses. Since student A is not going to re-enroll his data vanishes along with the course data. When he does decide to enroll in new course all his information must be re-entered into the system.

What is Denormalization?

Now lets take a look at Database Denormalization. This is the process by with DBAs attempt to optimize the performance of the database by adding in redundant, or grouped, data. The advantages to this is that the data is stored in one table, as opposed to multiple smaller tables, which cuts back on the need for JOINS in your queries, resulting in faster SELECTS. It is also good to note that a single table allows for a more efficient index usage. With properly indexed columns, results can be filtered and sorted by utilizing the same index.

What are the downsides?

The downsides really aren't big, and for the most part can be easily solved. One thing you must consider is that in a denormalized database, data can be duplicated across many tables. While this will result in better indexing and faster SELECTS as explained above, it does make INSERTS and UPDATES a bit more complicated. This is where it comes down to weighing the pros and cons. It all comes down to a ratio of reads VS. writes. If you have high reads and low writes, then denormalized is the sure way to go. If you are about even, or if you have higher writes than reads, you can still go with the denormalized approach but it may require a bit more thinking and planning.

Which should I use?

By now you're probably wondering which one to use. We've looked at just a few pros and cons to both approaches, and really it comes down to an almost 50/50 scale. The solution to this is simple: The correct way is to utilize both the normalized and denormalized approaches depending on the situations. Most of you are probably disappointed by the lack of a climax ending, and you were probably thinking that I was about to advocate a denormalized database over a normalized one, but that simply isn't the point of this tutorial. The point was to introduce you to denormalization, and to get you thinking and approaching database design in a new way. Many people spend all their time tweaking configuration settings and trying to optimize queries (mainly JOIN statements, which at their heart is really a complex nested-loop), when in fact they could get a huge bump in performance by taking a moment to ask themselves, "Should this be normalized or denormalized?"

As a side note, I will say that knowing your database engines can be a big help in boosting performance too. Knowing when to use MyISAM or InnoDB, and knowing when you should use something like ARCHIVE which only allows INSERTS and READS. At the end of the day the best performance boost you can give yourself is properly planning out your database layout upfront. See my tutorial An Introduction To MySQL Storage Engines.

Linux 4.x podría ver su nacimiento en 3 años

"La espera entre Linux 2.x y 3.x fue larga, pero la espera para Linux 4?

Bueno, eso sólo será cuestión de tres años, de acuerdo con Linus Torvalds.

"Es sólo mentalmente mucho más fácil para las personas para recordar el número pequeño ", dijo Torvalds durante la conferencia LinuxCon en San Diego [ miércoles anterior, según el sitio SLASHDOT.ORG].

" Haremos 4,0 en tres años, tal vez cuando los subnúmeros de los releases, hayan crecido a los 20's y nuestros cerebros débiles no pueden manejar la situación."
