Do you dream of balancing the load of your requests across a PostgreSQL cluster? Either way, we've got the solution for you.

Clever Cloud is proud to introduce the native support of Pgpool-II on all application instances, for no additional fee.

<span id="more-3001"></span>

<a href="https://www.clever.cloud/developers/deploy/addon/postgresql/pgpool">See the Clever Cloud documentation on Pgpool-II</a>.
<h2 id="what-is-pgpool-ii">What is Pgpool-II?</h2>
It is a middleware that comes in between your application and your PostgreSQL database (<a href="https://www.pgpool.net/mediawiki/index.php/Main_Page">official website</a>). As its name suggests, it <em>pools</em> your app's connections to PostgreSQL, by saving and reusing them, and letting them wait when they are too many.

Pgpool-II also serves as a load balancer for PostgreSQL replicas for superior scaling. More on this below.

Pgpool-II now works out of the box on all Clever Cloud machines. Only exception: if you use docker, you'll have to configure the Dockerfile yourself.
<h2 id="no-more-connection-refused">No more <code>connection refused</code></h2>
Pgpool-II overall smoothens the use of PostgreSQL.
<ul>
 	<li><strong>Accessed on a Unix socket</strong>: faster than a TCP socket. Gotta chase those nanoseconds.</li>
 	<li><strong>Connection reuse</strong>: Pgpool saves connections and reuses them when similar ones come in (same user, same database…).</li>
 	<li><strong>Managing exceeding connections</strong>: Normally, PostgreSQL takes only so many concurrent connections, and discards any additional ones, which compromises the app. Pgpool-II, instead, queues the excess connections for later. No more <code>connection refused</code>.</li>
</ul>
<h2 id="what-do-i-have-to-do">What do I have to do?</h2>
Barely anything. By changing only one environment variable in your code, your app will send its requests to Pgpool-II directly.

In a typical PHP app, you would connect to a PostgreSQL add-on by doing:
<pre><code class="language-PHP">$host = getenv("POSTGRESQL_ADDON_HOST");
</code></pre>
You just need to change that into:
<pre><code class="language-PHP">$host = getenv("CC_PGPOOL_SOCKET_PATH");
</code></pre>
That's all there is to change in your code. User, password, all other calls to environment variables remain the same. See <a href="https://www.clever.cloud/developers/deploy/addon/postgresql/pgpool/#usage">the doc</a> for details.

Now in the Clever Cloud Console, go to your app's environment variables, set <code>CC_ENABLE_PGPOOL</code> to <code>true</code>, and you're good to go!
<h2 id="load-balancing-lets-go-big">Load balancing: let's go big</h2>
Suppose your web app is BIG. You've got a few <code>INSERT</code> queries to make (registering a new customer for instance), and a ton of <code>SELECT</code> queries (searches, filling pages with products, you name it). It becomes wise to create <em>replicas</em> of your database, a PostgreSQL feature. These identical instances, called <em>followers</em>, are exact copycats of your <em>leader</em> database. On the graph they are called <em>primary</em> and <em>standby</em>, respectively. There can be several <em>standby</em> nodes.

<center>
<img style="width: 600px;" src="https://cdn.clever-cloud.com/uploads/2021/08/pgpool.png" /></center>

Do you dream of balancing the load of your requests across a PostgreSQL cluster? Either way, we've got the solution for you.

Clever Cloud is proud to introduce the native support of Pgpool-II on all application instances, for no additional fee.

<span id="more-3001"></span>

<a href="https://www.clever.cloud/developers/deploy/addon/postgresql/pgpool">See the Clever Cloud documentation on Pgpool-II</a>.
<h2 id="what-is-pgpool-ii">What is Pgpool-II?</h2>
It is a middleware that comes in between your application and your PostgreSQL database (<a href="https://www.pgpool.net/mediawiki/index.php/Main_Page">official website</a>). As its name suggests, it <em>pools</em> your app's connections to PostgreSQL, by saving and reusing them, and letting them wait when they are too many.

Pgpool-II also serves as a load balancer for PostgreSQL replicas for superior scaling. More on this below.

Pgpool-II now works out of the box on all Clever Cloud machines. Only exception: if you use docker, you'll have to configure the Dockerfile yourself.
<h2 id="no-more-connection-refused">No more <code>connection refused</code></h2>
Pgpool-II overall smoothens the use of PostgreSQL.
<ul>
 	<li><strong>Accessed on a Unix socket</strong>: faster than a TCP socket. Gotta chase those nanoseconds.</li>
 	<li><strong>Connection reuse</strong>: Pgpool saves connections and reuses them when similar ones come in (same user, same database…).</li>
 	<li><strong>Managing exceeding connections</strong>: Normally, PostgreSQL takes only so many concurrent connections, and discards any additional ones, which compromises the app. Pgpool-II, instead, queues the excess connections for later. No more <code>connection refused</code>.</li>
</ul>
<h2 id="what-do-i-have-to-do">What do I have to do?</h2>
Barely anything. By changing only one environment variable in your code, your app will send its requests to Pgpool-II directly.

In a typical PHP app, you would connect to a PostgreSQL add-on by doing:
<pre><code class="language-PHP">$host = getenv("POSTGRESQL_ADDON_HOST");
</code></pre>
You just need to change that into:
<pre><code class="language-PHP">$host = getenv("CC_PGPOOL_SOCKET_PATH");
</code></pre>
That's all there is to change in your code. User, password, all other calls to environment variables remain the same. See <a href="https://www.clever.cloud/developers/deploy/addon/postgresql/pgpool/#usage">the doc</a> for details.

Now in the Clever Cloud Console, go to your app's environment variables, set <code>CC_ENABLE_PGPOOL</code> to <code>true</code>, and you're good to go!
<h2 id="load-balancing-lets-go-big">Load balancing: let's go big</h2>
Suppose your web app is BIG. You've got a few <code>INSERT</code> queries to make (registering a new customer for instance), and a ton of <code>SELECT</code> queries (searches, filling pages with products, you name it). It becomes wise to create <em>replicas</em> of your database, a PostgreSQL feature. These identical instances, called <em>followers</em>, are exact copycats of your <em>leader</em> database. On the graph they are called <em>primary</em> and <em>standby</em>, respectively. There can be several <em>standby</em> nodes.

Pgpool-II will direct the <strong>write queries</strong> to the <em>primary</em>, and dispatch the <strong>read queries</strong> to the <em>standby</em> nodes, thus balancing the load and increasing throughput.

Check these out!</p>
<span id="more-2967"></span>

<p>Since the <a href="https://www.clever.cloud/blog/company/2013/07/24/mongodb-on-clever-cloud/">introduction of MongoDB in 2013</a>, things have changed a little bit. In the beginning, a few plans were proposed for MongoDB. Then we introduced some updates and new names for the plans (remember &quot;Peanut&quot;, &quot;Shamrock&quot; etc. ?). Today, we have two major updates to release.</p>
<h2 id="numerous-new-plans">Numerous new plans</h2>
<p>From five plans, this is nineteen plans of managed MongoDB now available on Clever Cloud. Most of our users start with a simple &quot;dev&quot; plan to try things at the beginning. But as their needs are getting bigger. Jumping from a simple 1GB plan to a 100GB (when only 5GB were needed) didn&#39;t make any sense.</p>
<p>Now with the new migration tool, moving from a bigger instance without a heavy price jump is easier.</p>
<h2 id="encrypted-databases">Encrypted databases</h2>
<p>Now you can ask for encrypted at rest databases! The add-on file system can be encrypted using LUKS. The encryption mode is  XTS, which is reputed to be more resistant to <a href="https://en.wikipedia.org/wiki/Watermarking_attack">watermarking attacks</a>.</p>
<p>To get your MongoDB encrypted at rest, ask the support team. A UI will be soon available to make this option automatic. Stay tuned for more add-ons! ✌️</p>

										<content:encoded><![CDATA[<p><em>French version below</em></p>
<p>On Saturday 11 January, Denis Payre, the president of &#39;<a href="http://www.nouscitoyens.fr">Nous Citoyens</a>&#39; (a new French political movement) was a guest on French presenter Laurent Ruquier&#39;s show, &#39;On n&#39;est pas couché.&#39;</p>
<p>This new french political movement has been officially launched on the 10th of october 2013, and allow its members to be part of it, thanks to its collaborative website, developed by the parisian web agency <a href="http://www.sooyoos.com/">Sooyoos</a>.</p>
<p><span id="more-2846"></span></p>
<p>Coded with PHP, a few configuration steps on Clever Cloud made by Sooyoos were needed to get the app ready for the TV broadcast.</p>
<p>Usually, the app runs on a 2GB and 2CPU scaler type (scalers are the equivalent of instances on Clever Cloud). But the TV audience brought 2 massive peaks of visits.</p>
<p>Around midnight, the webapp scaled from a L scaler size to a XXXL scaler size (8 CPU, 16GB of RAM), in a few seconds.</p>

<p></center></p>
<p>In most cases, media exposure of this kind (over 30 mins for Nous Citoyens here) leads to a huge load on the servers of the sites concerned, causing slowing down, and in the worst cases, periods of unavailability. For those who are lucky enough to be able to foresee such a load, the solution is to prepare a migration of the site to a more suitable infrastructure.</p>
<p>Unfortunately, this is not always the case. Because some companies fell victim to the &quot;Capital effect&quot; (&#39;Capital&#39; is a popular magazine program on the French TV channel, M6). According to social networks, some of them often acknowledged several minutes of unavailability during the program.</p>
<p>However, the Nous Citoyens website, hosted on Clever Cloud, remained perfectly stable throughout Denis Payre&#39;s interview on France 2, and that despite the increase in traffic due to the millions of television viewers.</p>
<p>Clever Cloud, therefore, managed the increased load without problem, thanks to an automatic attribution of resources to the infrastructure of NousCitoyens.fr.</p>
<hr id="french">
<p><em>Version française</em></p>
<p>Samedi 11 janvier, Denis Payre le président de <a href="http://www.nouscitoyens.fr">Nous Citoyens</a>, un nouveau mouvement politique, a été reçu dans l&#39;émission de Laurent Ruquier &quot;<a href="http://www.france2.fr/emissions/on-n-est-pas-couche/videos/94952658">On n’est pas couché</a>&quot;.</p>
<p>Lancé officiellement le jeudi 10 octobre et déjà fort de plusieurs milliers d&#39;adhérents, Nous Citoyens propose à tous de devenir acteur du mouvement, notamment grâce à sa plateforme web collaborative conçue par l&#39;agence parisienne <a href="http://www.sooyoos.com/">Sooyoos</a>.</p>
<p>Développée en PHP, celle-ci repose sur Clever Cloud pour son hébergement. Avec quelques réglages simples, l&#39;agence Sooyoos a pu être en mesure de préaprer le site de Nous Citoyens à l&#39;émission de France 2, où était invité Denis Payre.</p>
<p>En temps normal, la plateforme repose sur une scaler (équivalent d&#39;instances chez Clever Cloud) de taille &quot;Large&quot;, soit 2Go de RAM et 2 vCPU dédiés. Mais face à la forte médiatisation, 2 grands pics d&#39;audience ont été enregistrés.</p>
<p>À partir de minuit, l&#39;application a migrée d&#39;une instance de taille &#39;L&#39; jusqu&#39;à &#39;XXXL&#39; (8 CPU, 16Go de RAM), en passant par les tailles intermédiaires, puis est redescendue petit à petit vers sa taille d&#39;instance habituelle.</p>
<p><center></p>
<figure>
    <img decoding="async" height="180" src="https://www2.cleverapps.io/app/uploads/2021/08/traffic-peak.png"><figcaption>Le pic de trafic rencontré à 0h15 pour NousCitoyens.fr</figcaption></figure>
<p></center></p>
<p>Dans la plupart des cas, une telle exposition médiatique (ici plus de 45 minutes pour Nous Citoyens) entraîne une charge momumentale sur les serveurs des sites web concernés causant des ralentissments, et dans le pire des cas, une indisponibilité.</p>
<p>En revanche, hébergé sur Clever Cloud, le site de Nous Citoyens est resté parfaitement stable tout au long de l&#39;interview de Denis Payre sur France 2, et ce malgré la montée conséquente du trafic due aux millions de téléspectateurs.</p>
<p>Malheuresement, il n&#39;en va pas de même pour tout le monde, certaines entreprises étant victimes de “l&#39;Effet Capital” par exemple sur M6, résultant en ralentissments ou indisponibilité de quelques minutes au cours de l&#39;émission. Pour ceux qui ont la chance de prévoir une telle charge, la solution est de prépaprer une migration du site sur une infrastructure adaptée.</p>

<p>Since the beginning, anyone can use mutual Clever Cloud databases for free because it was in beta.<br />
Actually, this test period is over and databases will be charged from July 1st 2013.</p>
<p><span id="more-2724"></span></p>
<p>In order to fit high performance needs, we will launch dedicated databases soon <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f642.png" alt="🙂" class="wp-smiley" style="height: 1em; max-height: 1em;" /></p>
<p>The finesse pricing is daily. It means that once you create a database, you are charged for one day usage, and so on.<br />
For example, a S database will cost 0,23 €/day.</p>
<p>The pricing plans for PostgreSQL and MySQL will be the following:</p>
<div class="table-db">

<p>You will be able to configure the number of Scalers dedicated to your database <a href="https://www.clever.cloud/pricing/" target="_blank" rel="noopener noreferrer">as you can do with apps</a>.</p>
<p>These databases will be more powerful, larger and more scalable than the mutualised databases.</p>
<hr />
<p><em>Version française</em></p>
<p>Depuis le début, tout le monde pouvait utiliser gratuitement les bases de données mutuelles sur Clever Cloud puisqu&#8217;elles étaient en beta. Désormais, cette phase de test s&#8217;achève et l’utilisation des bases de données sera facturée à partir du 1er juillet 2013.</p>
<p>Les tarifs pour une PostgreSQL et une MySQL seront les suivants:</p>

</div>
<p>L’ajustement du pricing est quotidien. Cela signifie qu’une fois que vous avez créé la base de données, vous serez facturé pour une journée d’usage, et ainsi de suite.</p>
<p>À titre d’exemple, une base de données de taille S coûtera 0,23 €/jour.</p>
<p>Pour répondre aux besoins de haute performance, nous lancerons bientôt des bases de données dédiées <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f642.png" alt="🙂" class="wp-smiley" style="height: 1em; max-height: 1em;" /></p>
<p>Il sera possible de configurer le nombre de Scalers dédiés à la base de données, comme il est déjà possible de le faire <a href="https://www.clever.cloud/fr/tarification/" target="_blank" rel="noopener noreferrer">avec les applications</a>.</p>
<p>Ces bases de données seront plus puissantes, plus scalables et auront plus de capacité de stockage que les bases de données mutualisées.</p>

<div style="text-align:center;font-style:italic">Another kind of &#8216;external&#8217; DBs</div>
</div>
<p>Until now, databases hosted on Clever Cloud were only available from within the hosted apps. Since it was impossible to use external DB management software, it was a bit cumbersome to import or export data.</p>
<p><span id="more-2844"></span></p>
<p>This era is over: right now, the services are available from outside!</p>
<p>Indeed, it means you will be able to use your favorite DB management tool. If you want to use our platform simply for host a database or if you have to access to your db for initial setup or migration, you can.<br />It also means you can use Clever Cloud as a pure <strong>Database as a Service</strong> (DBaaS) provider.</p>
<p>The current form (only available from within Clever Cloud apps) is<br />&quot;<em>dbname.engine</em>.internal&quot; (eg &quot;<em>customers.my</em>.internal&quot;).</p>
<p>The new domain names will follow this pattern:<br />&quot;<em>dbname.engine</em>.clvrcld.net&quot; (eg &quot;<em>customers.mysql</em>.clvrcld.net&quot;).</p>
<p>As for the ports, they stay the same (3306 for MySQL, 5432 for PostgreSQL).</p>
<p>Old domain names remain active for now (no sunset date is planned yet), but we strongly encourage you to make the switch.</p>
<p>We will indicate a date for the end of the internal databases services later.</p>
<p>The support remains at your service to help you tomigrate from .internal to clvrcld.net in your code.</p>
<p>Don&#39;t hesitate ton contact the <a href="mailto:support@clever-cloud.com">support</a> for more precisions <img src="https://s.w.org/images/core/emoji/17.0.2/72x72/1f609.png" alt="😉" class="wp-smiley" style="height: 1em; max-height: 1em;" /></p>

<p>Jusqu&#39;ici les bases de données hébergées dans Clever Cloud n&#39;étaient utilisables que depuis l&#39;application hébergée. Il était alors impossible d&#39;utiliser un outil de gestion de base de données externe, ce qui était fastidieux notamment pour les imports/exports.</p>
<p>Cette ère est révolue: désormais, les services sont accessible depuis l&#39;extérieur !</p>
<p>Concrètement, cela signifie qu&#39;il sera possible d&#39;utiliser l&#39;outil de management de votre choix. Si vous souhaitez utiliser notre plateforme uniquement pour héberger une base de données ou si vous devez accéder à votre base depuis l’extérieur pour l&#39;amorçage ou la migration de vos données, c&#39;est désormais possible.<br />Clever Cloud devient donc aussi fournisseur <strong>Database as a Service</strong> (DBaaS) !</p>
<p>La forme actuelle (seulement accessible depuis les applications Clever Cloud) est:<br />&quot;<em>dbname.engine</em>.internal&quot; (ex &quot;<em>clients.my</em>.internal&quot;).</p>
<p>Les nouveaux noms de domaine adopteront désormais cette forme:<br />&quot;<em>dbname.engine</em>.clvrcld.net&quot; (ex &quot;<em>clients.mysql</em>.clvrcld.net&quot;).</p>
<p>En ce qui concerne les ports, ils restent les même (3306 for MySQL, 5432 for PostgreSQL).</p>
<p>Nous préciserons une date de fin des services des bases de données internes ultérieurement.</p>
<p>Le support reste à votre service pour vous aider à migrer de .internal vers le clvrcld.net dans votre code.</p>
