Classement des clouds JDN / CloudSc

Classement des clouds JDN / CloudScreener : la méthodologie
Chaque mois, le JDN publie en partenariat avec CloudScreener le classement Performance / Prix / Niveau de service des principaux clouds.

Classement mensuel Performance / Prix / Niveau de service
L'indice général est établit à partir de la moyenne des indices Niveau de service, Performance et Prix.
Classement des Niveau de service
L'indice moyen de niveau de service des fournisseurs est calculé en fonction d'une liste de critères qualitatifs prédéfinis. Ces critères sont répartis dans quatre catégories : Présence géographie, Certifications, SLA annoncés, Largeur de gamme. L'indice moyen de niveau de service est la moyenne des indices de ces quatre catégories. Chaque catégorie a la même pondération dans le calcul de cet indice moyen de Niveau de Service.
Pour les critères de présences géographiques et de certifications, l'indice est calculé en fonction de la complétude du fournisseur par rapport aux critères demandés
Pour le critère de SLA : un indice de 100 est attribué pour un SLA de 100% et un indice de 25 pour un SLA de 99,5%. Un fournisseur ne communiquant pas de SLA aurait un indice de 0. L'indice SLA de chaque fournisseur est calculé en fonction de la position du niveau de SLA communiqué dans cet espace de valeurs. L'indice de Largeur de gamme (en vCPU et Ram) est calculé en fonction de la taille des gabarits proposés par chaque fournisseur.
Classement performances
Les indicateurs CloudScreener prennent en compte les valeurs moyennes des mesures, ainsi qu'un coefficient de variation (écart type/moyenne), ainsi qu'une valeur étalon, considérée comme l'état de l'art par CloudScreener et Cedexis. En complément de la performance moyenne d'un fournisseur, ce coefficient permet de percevoir la stabilité de l'infrastructure. L'indice de performance pour chaque critère (hors réseau) correspond ainsi à la différence entre la valeur moyenne corrigée de l'écart type et la valeur état de l'art. Cet indice est capé à 100 pour toute valeur au-delà de l'étalon.

Classification of clouds JDN / CloudScreener: methodologyEvery month, the JDN publishes in partnership with CloudScreener the ranking Performance / price / service level of the main clouds.Monthly ranking Performance / price / service levelThe general index is based on the average level of service, Performance, and price indices.Service level rankingsThe average level of service providers index is calculated based on a list of predefined quality criteria. These criteria fall into four categories: Presence geography, Certifications, SLA announced, wide range. The average service level index is the average of the indexes of these four categories. Each category has the same weighting in the calculation of the average index level of service.For geographic presences and certifications criteria, the index is calculated based on the completeness of the supplier against the criteriaFor the criterion of ALS: an index of 100 is attributed to an SLA of 100% and an index of 25 for a 99.5% SLA. A supplier providing no SLA would have an index of 0. The SLA of each provider index is calculated based on the position of SLA level provided in this value space. The index of wide range (in vCPU and Ram) is calculated based on the size of the templates offered by each provider.Ranking performanceCloudScreener indicators take into account the average values of the measures, as well as a coefficient of variation (gap type/medium), as well as a gold standard, considered State of the art by CloudScreener and Cedexis. In addition to the average performance of a provider, this coefficient allows to perceive the stability of infrastructure. The performance index for each criterion (off-grid) thus corresponds to the difference between the average value of the standard deviation and the State of the art value. This index is capped at 100 for any value beyond the standard.

Classification of clouds JDN / CloudScreener: Methodology
Each month the JDN published in partnership with CloudScreener ranking Performance / Price / Service Level of the main clouds.

Ranking Monthly Performance / Price / Service Level
The general index is established from the average index level of service, performance and price.
Ranking Service level
the average index of supplier service level is based on a list of predefined quality criteria. These criteria are divided into four categories: geography presence, Certifications, announced SLA range width. The average index level of service is the average of the indices of these four categories. Each category has the same weighting in the calculation of the average index of service level.
For criteria of geographical presences and certifications, the index is based on the completeness of the supplier against the criteria required
for the SLA criteria : an index of 100 is attributed to an SLA of 100% and an index of 25 for an SLA of 99.5%. A supplier not communicating with ALS have an index 0. The SLA index of each supplier is based on the position of the SLA level statement in this space values. The index range width (in vCPUs and RAM) is calculated based on the size of the templates offered by each provider.
Rank performance
The CloudScreener indicators take into account the average values ​​of the measures, and a coefficient of variation (standard deviation / mean) and a standard value, which is considered state of the art by CloudScreener and Cedexis. In addition to the average performance of a supplier, this coefficient allows to perceive the infrastructure stability. The performance index for each criterion (off-grid) and corresponds to the difference between the average value of corrected standard deviation value and the state of the art. This index is capped at 100 for all values ​​beyond the standard.
