Excerpts from an Interview with John Derrick, CEO Jelastic.

John has led multiple private and public companies to success as CEO, COO, and Advisor. Extensive business leadership experience in private and public cloud, big data, data base, and enterprise markets.

[…]

What are the problems facing those CTOs today?

Fundamentally, businesses use technology to achieve competitive differentiation, so the corporate IT department has become a service provider to the rest of the organization. Part of its function is to provide a stable, scalable, highly available platform for deployed applications but it also needs to provide developers with an infrastructure that supports agile development and deployment of new applications.

If developers can’t get the service they need from the internal IT department, they start to go elsewhere and develop applications in the public cloud or wherever they can get resources quickly.  This leads to “shadow” IT departments emerging bringing with them a myriad of other problems, not least potential security breaches.

So what are the choices available?

Well, any CTO can take the conservative choice, and stick with existing private virtualization solutions. But the complexity of management, lack of easy scalability and sheer cost of those solutions simply don’t make sense any more.  So enterprises really have a choice between cloud infrastructures, public, private or hybrid.

Even then, messaging in the market is confused with at least two major open-source groups providing building-block solutions that address cloud platforms and infrastructures and then a whole host of smaller companies providing cloud components, maybe a PaaS, maybe infrastructure, perhaps management or billing, that either complement one of the open-source stacks or proprietary solutions.

So lots of choices, how does the CTO decide?

Well that’s the point.  Some of the building-block solutions are major strategic commitments that require complex and lengthy integrations with no guarantees that legacy applications will be supported or that new innovations will be integrated effectively. Proprietary solutions almost always involve coding to custom APIs that lock in the enterprise to that solution.

So CTOs must ask the following questions:

What are my goals for my cloud implementation today?

  • Regain control?
  • Enable agile development?
  • “Cloudify” legacy applications?
  • Accelerate new application development?
  • Private cloud only?
  • Run with existing virtualization solution?
  • Hybrid cloud future?
  • Self-management for developers?

What functionality is non-negotiable?

  • Seamless scalability
  • High-availability
  • Simple management
  • Security

How can keep my infrastructure flexible?

  • No code lock in
  • No APIs to code to
  • Open technology where available

[…]

Where does Jelastic fit into all this?

Jelastic provides an alternative choice to complex and costly cloud implementations.  Our Platform-as-Infrastructure solution gets enterprises up and running with a private cloud quickly and simply, and offers all of the enterprise-class scalability, availability and manageability features that they need.

Our approach has been to build a cloud implementation from the ground up, using the best open technologies, providing a combination of IaaS and PaaS that are integrated.  By combining the technologies, we are able to provide new efficiencies and features that go beyond current cloud implementations.

[…]

What industry trends do you see in 2014 for the cloud?

Many analysts are predicting a continuation of the blurring of the lines between PaaS and IaaS and, of course, we agree with that.  But I also see continued confusion in the marketplace as the cloud wars continue to muddy the waters. I’d also predict further vendor consolidation as larger players see fit to bolster their offerings with new technology.

  • Effektive Kosten, exakt und stundengenau berechnet – Dadurch zeichnet sich die Cloud aus.

    Wenn Sie Jelastic als hochverfügbare Hosting Plattform nutzen, kaufen Sie keine starren Ressourcen. Ihre Anwendung hat exakt soviel CPU Leistung, RAM und Festplattenplatz zur Verfügung, wie sie in diesem Moment braucht. Dabei spielt es keine Rolle, ob Sie 5 Server, 10 oder 100 Server in Jelastic nutzen. Für uns, und Sie, zählt nur der stundengenaue Verbrauch an CPU, RAM und HDD.

    Wie es genau funktioniert, zeigen wir in diesem kurzen Video

  • Public IP oder Shared-Resolver in Jelastic

    Softwareentwicklung ist immer eine Frage von Entscheidungen, vor allem jetzt, wo die IT über so viele Lösungen verfügt. Um erfolgreich zu sein, müssen Sie die richtige Wahl treffen, beginnend bei Software und Tools bis hin zu Serversystemen über die Wahl der richtigen Cloud und Technologie für Ihr Projekt.

    Die Jelastic Cloud bietet Ihnen viele Vorteile, angefangen von Hochverfügbarkeit über Skalierung bis hin zu stundengenauer Abrechnung ohne Vertragsbindung. In diesem Artikel geht es um die Unterschiede zwischen unseren Shared Resolvern und einer eigenen öffentliche IPv4 IP für Ihre Umgebungen in Jelastic.

     

    Jelastic Shared-Resolver

    Lassen Sie uns mit dem Standard beginnen, welchen wir kostenfrei allen Kunden zur Verfügung stellen, die Shared-Resolver.

    Der Jelastic Shared-Resolver ist ein NGINX Proxy-Server zwischen dem Client (z.B. Browser) und Ihrer Anwendung in Jelastic. Der Shared-Resolver verarbeitet alle eingehenden Anfragen an Umgebungen in Jelastic ({user_domain}.jelastic.dogado.eu, z.B. meinedomain.jelastic.dogado.eu) die nicht über eine öffentliche IP Adresse verfügen.

    Jelastic_Cloud_End-User-Request-2

    Jelastic Cloud Shared-Resolver

     

    Vorteile

    Kostenlose Nutzung: Jelastic Shared-Resolver werden kostenlos zur Verfügung gestellt. Dies ist eine großartige Möglichkeit um während der Entwicklung Kosten und Zeit zu sparen.

    Sofort verfügbar: Sie müssen keine Anpassungen oder nachträgliche Konfigurationen machen. Unsere Resolver sind vorkonfiguriert und passen sich automatisch an Ihre Umgebung in Jelastic an.

    Hochverfügbar und Skalierbar: Um höchste Verfügbarkeit zu garantieren, verwenden wir in der Jelastic Cloud mehrere synchronisierte Resolver um eingehende Anfragen parallel zu verarbeiten. Alle Anfragen werden über mehrere Resolver entgegengenommen und verteilen die Last gleichmäßig auf alle Systeme.

     

    Jelastic_Cloud_Resolver-HA-GIF2

    Jelastic Cloud Hochverfügbar & Lastverteilung

     

    Limitierungen

    Anzahl der Verbindungen: Um Ihre Anwendung vor DDoS-Attacken zu schützen, leiten wir maximal 50 gleichzeitige Anfragen durch unsere Resolver an Ihre Umgebung in Jelastic weiter.

    Datei-Upload begrenzt: Wir haben die maximale Dateigröße auf 8MB beschränkt. Größere Uploads sind über unsere Shared-Resolver nicht erlaubt.

    Öffentliche IP

    Für eine sicherere Arbeit mit Ihrer Produktivumgebung in Jelastic empfehlen wir immer eigene öffentliche IP Adressen für alle Instanzen zu nutzen. Jelastic unterstützt dabei den weltweiten Standard IPv4 (Internet Protocol Version 4). An IPv6 arbeiten wie bereits, so das Jelastic auch in dieser Richtung zukunftssicher ist.

    Durch die Nutzung einer eigenen IP Adresse für Ihre Umgebungen haben einen direkten Einstiegspunkt in Ihre Umgebungen. Das bietet einige Vorteile, gerade was die Individuelle Lastverteilung für Ihre Umgebungen angeht.

     

    Jelastic_Cloud_End-User-Request

    Jelastic Shared-Resolver vs public IP

     

    Vorteile

    Eigene SSL Zertifikate: Mit einer eigenen öffentlichen IP können Sie auch eigene SSL Zertifikate einbinden um so Ihre Webseite o. Anwendung sicherer zu machen. Natürlich für Ihren eigenen Domainnamen wie z.B. https://www.meine-jelastic-umgebung.de anstelle von https://meine-jelastic-umgebung.jelastic.dogado.eu

    FTP-Unterstützung: Wenn Sie eine eigene öffentliche IP für Ihre Instanzen nutzen, können Sie direkt via FTP und sFTP auf die Daten in Jelastic zugreifen.

    Remote-Zugriff auf Datenbank: Eine eigene IP Adresse erlaubt es Ihnen direkt auf Ihre Datenbank zuzugreifen. So können Sie z.B. große Datenmengen Importieren und Exportieren, Sicherungen machen und mit Drittanbieter-Tools auf die Datenbank für weitere Analysen zugreifen.

    Remote-Debugging: Einfaches und schnelles Remote-Debugging direkt aus Ihrem IDE heraus.

    WebSockets: WebSockets ermöglichen den Aufbau einer lang anhaltenden TCP Socket-Verbindung zwischen dem Client und dem Server, um Nachrichten bidirektional, vollduplex und mit wenig Overhead direkt zu übermitteln. WebSockets machen Ihre Anwendung schneller, effizienter und skalierbarer.

     

    Einschränkungen

    Kosten für IP Adressen: Für die Nutzung eigener IP Adressen in Jelastic berechnen wir eine geringe Gebühr. Natürlich stundengenau und ohne Vertragsbindung.

    Kein Domain-Swap: Wenn Sie eigene öffentliche IP Adressen nutzen, können Sie nicht mehr einfach die Domain in Jelastic on-the-fly switchen. Sie müssen dann die DNS Daten Ihrer Domain ändern.

    Manuelles aktivieren der IP: Über den Topologie-Manager müssen Sie die IP für jede Instanz in Ihrer Jelastic Umgebung manuell aktivieren.

     

    Jelastic_Cloud_Swithing-on-Public-IP

    IPv4 aktivieren

    Nach der Aktivierung wird Ihnen die IP neben der Instanz über das kleine Info-Feld direkt angezeigt.

    Jelastic_Cloud_Find-Jelastic-Public-IP

    IP anzeigen lassen

     

    Fazit

    Wir empfehlen den Einsatz des Jelastic Shared-Resolver für Test und Development Umgebungen. Für Live-Umgebungen ist es ratsamer eigene öffentliche IP Adressen zu nutzen. Dies bringt Vorteile in Geschwindigkeit und Sicherheit für Ihre Webseite resp. Anwendung. Sie können so eigene Lastverteiler aktivieren und ganz nach Ihren Bedürfnissen konfigurieren.

    Am Ende ist es jedoch Ihre Entscheidung. Wir hoffen das wir Ihnen mit diesem Artikel die Entscheidung ein bisschen einfacher machen konnten.

  • High Availability WordPress with Jelastic

    It’s no secret that WordPress is one of the most used CMSs in the world.

    We will use a Memcached node, two Apache servers, an NGINX load balancer and two replicated MySQL databases. In this case if one Apache server fails, the sessions are stored for backup on the Memcached node. The other server can fetch the sessions from Memcached and then proceed serving the session. An NGINX load balancer distributes the traffic across the cluster. The MySQL master-slave replication mechanism improves the performance, the data security and the fail-over capabilities. read more…

  • Thank you Thomas for your great feedback.

    “Jelastic provides a huge set of programming languages (e.g., Java, Ruby, PHP), databases (e.g., MariaDB, PostgreSQL, MongoDB, and CouchDB) and premium services such as high availability and load balancing. I use Jelastic for some of my projects and I am very happy with their service even that an API to manage their PaaS infrastructure is not existing. However, this will be changed in the future as I was told by a Jelastic guy.” Thomas King

    With the growing insights into the PRISM program the reluctance against US-based cloud services is raising on a rapid speed in Germany. Especially, from companies and individuals located in Germany my perception is that they try to avoid US-based cloud services wherever possible. For instance, the very popular German business contact networking plattform Xing just started a data privacy campaign stating that all servers are located in Germany. As sign that this is of high interest for Xing customers is that this campaign is shown on the top of the first page which you see when you log in to their service. This is just one example that services using US-based data storage or computing power are considered harmful.

  • To meet all of the requirements of your PHP application, sometimes you need to add custom modules. Modular architecture is one of the major reasons for the Apache server’s global popularity. Most web sites are powered by apache Webserver. Such architecture allows easy extension with optional functionality, third party add-ons, and custom modifications. A new PHP module isn’t always the right solution for every problem. If you are sure this is the only solution for your PHP application, Apache’s architecture is designed in such a way that it’s should not be a daunting task. Today we’ll show you how to enable custom PHP modules in Jelastic Cloud Platform.

    Note: Here you can see the full list of the Apache and NGINX modules available in Jelastic by default.

  • Tatiana ZhakToday’s dogado Customer spotlight comes to you from Russia.

    Some time ago we had a chat with Tatyana Zhak, a web developer from Sugar Games. Sugar Games is famous for its fun social network games development. Their project “My Perfect Wedding” (a social network dress up game) migrated to Jelastic a few months ago. It is very popular in such Russian social networks as Odnoklassniki, MailRu and Vk. This game has more than 3 million installations and more than 40K DAU (daily active users). Tatyana has kindly shared the reasons behind and the outcomes of their hosting changes.

    Here’s a short summary

    [...] Server structure creation took about 10-15 minutes.  [...]  Also I want to mention that we didn’t change the application code or install any software like we had to do for Amazon.

    [...] few weeks ago we contacted our hoster dogado in order to increase the maximum limit for MySQL because 64 cloudlets were not enough for us. They immediately  [...] increased the limits to 256 cloudlets [...] After that we didn’t have any overloads.

    [...] We are more than just satisfied with Jelastic:) If any issues occur, your support team responds very quickly.

    [...] Our hosting expenses were reduced 50% compared with the costs at Amazon.
